The catch
Gaggia Classic Pro E24
Without a factory PID, managing temperature is something you have to practice.
Side by side
Gaggia Classic Pro E24 vs Breville Dual Boiler compared: Breville fits repeat milk drinks, Gaggia takes less counter room
Quick verdict
For temperature control and milk drinks made repeatedly, the Dual Boiler fits better. The Gaggia makes a strong case if a smaller, simpler 58mm platform and an established parts ecosystem count for more to you.

The catch
Breville Dual Boiler
Expect to buy a capable grinder separately, and expect it to occupy far more counter than a compact thermoblock machine.

What this page compares
Choose between a compact traditional single boiler and independent boilers with precise control for high throughput.
This one comes down to heating and temperature first, then to the limits of your own setup.
Day to day
How each one fits your routine
Making two milk drinks shows how the boilers differ
Say you are making milk drinks for two people. With Dual Boiler you can run extraction and steaming at the same time. The E24's single boiler makes you do those jobs in sequence. Go with Breville if you want that overlap and can handle both actions. Gaggia is still a sensible hands-on pick if you make a drink at a time. A second boiler does not grind or tamp the next puck, so preparation can remain the bottleneck.
Where this comes from
Breville’s independent brew and steam systems are what allow brewing and steaming to run concurrently. The E24 brass boiler fits a sequential routine. That backs a conclusion about the order of work and does not invent any seconds-saved figure.
A matching 58 mm label is just where an accessory check begins
If you are coming from another espresso machine, you may already own a 58 mm tamper or baskets. Both machines in this comparison use that nominal portafilter diameter, so it should not be what separates them. Confirm the exact basket and portafilter fit before reusing tools, and then decide based on workflow. Breville's independent temperature controls matter if you deliberately adjust brew conditions, while the E24 keeps controls more hands-on.
Where this comes from
The official specifications for both list 58 mm portafilters. Breville additionally specifies independent PID control of its brew boiler and heated group. Nothing in the evidence shows that portafilters or baskets are interchangeable across brands.

Trade-offs
What each pick costs you
With Gaggia Classic Pro E24
- You need your own grinder, and its single boiler has to shift temperature when you switch from brewing to steaming.
With Breville Dual Boiler
- Compared with simpler machines, the boilers, group and cleaning routines demand more warm-up time and upkeep.
