These two land on more final shortlists than almost any other pair of dual boilers we sell. Both are flagship E61 machines, both pull world-class espresso, and both will still be working in twenty years. So the question is not which one is "better" — it is how you want to make coffee.
We sell and service both from our Brisbane showroom. We have pulled shots on each and rebuilt both on the bench, and we have both on display side by side. What follows is the head-to-head we give customers down to these two — the genuine differences (the Bianca's built-in paddle versus the Synchronika's German build and bigger steam boiler), current AU pricing with a real gap, and the in-house service picture for both. No house favourite. The right answer comes down to which machine fits the way you want to work.
Buy the Lelit Bianca V3 if: you want pressure profiling built in — the factory paddle is the reason to buy it — you're value-conscious between the two, or you want the most hands-on, experiment-friendly machine.
Buy the ECM Synchronika II if: you want the premium German build feel, you care more about consistent shot quality than paddle manipulation, you steam a lot of milk back-to-back, or you value fast warm-up and a machine that will outlast most of what you own.
Both are excellent dual boilers. The cup difference between them is narrow — what actually separates them is the paddle, steam headroom, build feel and price. Unlike some matchups in this bracket, price is a real axis here: the Bianca lands around $1,550 under the Synchronika.

Both are full dual boilers with independent brew and steam PIDs, rotary pumps and plumb-in capability — the same fundamental architecture. Pump type and plumbing are not differentiators here; both are rotary and both plumb in. (Older posts that list the Bianca as a vibration-pump machine are wrong — the V3 is rotary.) What actually separates them is the paddle, the steam boiler and the build, so that is where this comparison lives.
If you take one thing from this comparison, take this. The single biggest functional difference between these two machines is flow control, and on the Bianca V3 it is standard.
The Bianca V3 has a manual paddle built into the group — a needle valve that lets you throttle water flow by hand across the whole shot. You lift it for a long, gentle pre-infusion to settle the puck, open it to pull, and taper it off at the end to chase sweetness and clarity. With flow control you are the algorithm: you can ramp pressure to rescue a channelling shot, hold a low-pressure bloom on a light roast, or shape a declining profile that a pump-only machine simply can't produce. It is the standout feature in this price bracket, and on the Bianca it is fitted from the factory at no extra cost. (Our pressure profiling guide walks through the technique in detail.)
The Synchronika II does not have flow control as standard — but it is not locked out of it either. ECM makes an OEM flow control kit for the Synchronika: a genuine ECM part, not a third-party add-on. We can fit it at the time of purchase or retrofit it later. So the honest framing is not "has it versus doesn't" — both machines can flow-control. The difference is that the Bianca's paddle is standard and integrated, designed into the machine from the start, while the Synchronika's is a paid factory option that adds to the price.
For a buyer who wants to profile shots, that makes the maths simple: the Bianca brings the capability in at a lower price with nothing to add. For a buyer who isn't sure they'll use a paddle, the Synchronika lets them skip the cost now and add the genuine ECM kit later if they catch the bug. Both run a classic E61 group, so the lever feel and pre-infusion behaviour are familiar territory either way — see our E61 group head guide for why it remains the most loved group in prosumer espresso.
This is where the Synchronika makes its case. ECM build their machines in Germany under the "Manufacture" banner, and the Synchronika II is one of the most solidly screwed-together prosumer machines on the market. The fit and finish is tight, the panels are heavy-gauge stainless, the switches and fittings feel deliberate, and the whole thing has a restrained, almost commercial aesthetic — no flourishes, just precision. If you value the feel of a serious German-built machine, the Synchronika delivers it the moment you touch it.
The Bianca takes a different tack. Lelit build it in Italy, and the V3 is unapologetically design-forward: stainless steel dressed with walnut accents on the paddle, feet and side panels, with the height-adjustable water tank and a profile that's made to be looked at as much as used. It is beautifully made — this is a flagship, not a budget machine — but the character is warmer and more expressive than the ECM's. Where the Synchronika feels like a tool, the Bianca feels like a piece of equipment you chose partly because you like looking at it.
On raw longevity there is genuinely nothing to separate them. Both are brass-and-stainless machines built to run 15 to 20 years with regular servicing, and both use the universally serviceable E61 group. If we're being honest rather than worshipful, the Synchronika feels the more commercial and overbuilt of the two, and the Bianca the more characterful — but neither is fragile, and neither will let you down. This one comes down to taste: restrained German engineering, or expressive Italian design.
Both machines are full dual boilers, so each holds brew and steam at independent, PID-stable temperatures and you never wait for one to catch up with the other. But the boiler sizes differ, and that's where the Synchronika claws back a genuine edge.
On steam, the Synchronika II is the stronger machine. Its 2-litre steam boiler is noticeably larger than the Bianca's 1.5 litres, which means more headroom and faster recovery when you're texturing milk back to back. If your weekends involve steaming four or five jugs in a row, that extra capacity shows up as more relentless steam pressure and less waiting. Both produce excellent microfoam, and for a household making one to three milk drinks at a sitting the Bianca's 1.5-litre boiler is more than ample — but if you steam in volume, the ECM is the better steamer and we'll say so plainly. (Our steam power guide covers how boiler size translates to real milk performance.) The Bianca answers with a marginally larger brew boiler — 0.8 litres versus 0.7 — which is a smaller, less practically decisive difference.
On warm-up, the Synchronika wins on paper. It uses ECM's fast-heat system — cartridge heaters built into the E61 group — to reach brewing temperature in around 6.5 minutes at the group, with the whole machine settled in roughly 9–10 minutes. The Bianca V3 is a conventional E61 and wants closer to 20–25 minutes to fully heat-soak. That's a real difference, and if you want espresso now from cold, the ECM gives it to you. In practice, though, most Bianca owners just run it off a timer plug so it's hot before they wake up, which neutralises the gap for daily use. It's a genuine ECM advantage — just rarely the thing that decides the purchase. Both run independent dual PIDs; if that's new to you, our PID controller guide explains why it matters.
Live figures as of writing:
Both brands run sales, so the exact numbers move — but the shape doesn't. The Bianca lands around $1,550 under the Synchronika, and it brings the factory paddle in for that lower price. The Synchronika asks more, and what you're paying the premium for is the German build feel, the bigger steam boiler and the fast warm-up. Unlike some pairs in this bracket that sit within a few hundred dollars of each other, here price is a real axis in the decision — be straight with yourself about whether the Synchronika's advantages are worth $1,550 to you, because the Bianca is a flagship in its own right, not a compromise.
Buy the Synchronika II if the build feel and steam capacity matter more to you than a standard paddle. It's the machine for the buyer who wants premium German manufacture they can feel in every panel and switch, and who is more interested in pulling consistent, repeatable shots than in manually profiling each one. If you steam a lot of milk back to back, the larger 2-litre steam boiler is a real, daily advantage. If you want espresso fast from cold, the fast-heat group gets you there in minutes.
It's also the choice if you like the idea of flow control but aren't sure you'll use it — you can buy the machine now and add the genuine ECM OEM kit later if you decide you want it, rather than paying for a paddle you might leave alone. You're spending more, and what you get for it is the most overbuilt, commercial-feeling machine of the two, plus the steam and warm-up edge. It will comfortably outlast most of what you own.
Buy the Bianca V3 if you want pressure profiling built in. The factory paddle is the reason to buy this machine — it's the standout feature in the price bracket, it's standard rather than an extra, and if you're the kind of person who wants to experiment with pre-infusion, declining profiles and channelling rescues, nothing else here gives you that out of the box. It is the most hands-on, experiment-friendly machine of the two by a clear margin.
It's also the value pick. At around $1,550 less than the Synchronika, the Bianca is the better-value entry into true dual-boiler ownership, and you're not giving up much to get there — same E61 group, same independent dual PIDs, same rotary plumb-in build, plus that paddle and the design-forward stainless-and-walnut looks. If you're value-conscious between the two, or you simply want the most engaging machine to make coffee on, the Bianca is the answer. The Synchronika's edges in steam volume and warm-up are real, but for most home baristas the paddle and the price win the day.
For most buyers, yes — if you're going to use the paddle. The Bianca V3 brings factory flow control in at around $1,550 less than the Synchronika II, and that paddle is the standout feature in this price bracket. The Synchronika earns its premium on build feel, a bigger steam boiler and fast warm-up — all real, but the Bianca competes hard on the things most home baristas notice day to day.
Yes. The Synchronika II doesn't have flow control as standard, but ECM makes an OEM flow control kit for it — a genuine ECM part, not a third-party add-on. We can fit it at the time of purchase or retrofit it later. It adds to the price, and unlike the Bianca's paddle — which is built into the machine from the start — it's an optional extra.
The Synchronika II has the larger steam boiler — 2 litres versus 1.5 on the Bianca V3 — so it has more headroom for back-to-back milk texturing. Both produce excellent microfoam; the difference only shows up when you're steaming several jugs in a row.
The Synchronika II. It uses ECM's fast-heat system — cartridge heaters in the E61 group bring it to brewing temperature in around 6.5 minutes at the group. The Bianca V3 is a conventional E61 and wants roughly 20–25 minutes to fully settle. Most Bianca owners just run it off a timer plug, so in practice it rarely decides the purchase.
