A thermoblock against a dual boiler — two philosophies of the same morning.

The counter’s vote
Looks barely figure in either machine’s record — the counter can sit this one out.
Decent DE1+: Tech-forward minimalist aesthetic appeals to the engineering-minded crowd; polarizes traditionalists who see it as a gadget over a machine.
Classic GT: Premium stainless chassis and compact dual-boiler footprint appeal as a "real machine" counter presence; reveals preference for pro-style build over appliance aesthetics.
Only the Classic GT: brewing and steaming at once.
Only the Decent DE1+: flow control.
Only the Decent DE1+: the standard 58mm ecosystem.
Where they tie: milk & steam · ready when you are · forgiving to learn on · built to last · push-button convenience — don’t let a spec sheet invent a difference.
On the counter
The size difference, to scale
So — which one?
Take the Decent DE1+ if —
- The shot itself is the hobby
- You want more dials, not fewer
- Baskets, tampers and mods transfer, forever
Take the Classic GT if —
- You host, and drinks come in rounds
- It has to just work, every day
- You plan to fix, not replace
- Mornings run on a clock
Both columns reading true? Take the one your gut already picked — then stop reading reviews. Fresh beans will move the cup more than this choice will.
Known weak points
Decent DE1+
Solenoid valve failures reported in early units; heating element lifespan varies; Bluetooth connectivity issues on some firmware revisions; water line calcium buildup affecting group head.
