Two mid-range-tier espresso machines for beginner and enthusiast / dialed-in, compared on the specs that actually decide the buy — not review fluff.

Both are mid-range-tier espresso machines suited to beginner and enthusiast / dialed-in. The De'Longhi La Specialista Maestro has a thermoblock / thermocoil and the Profitec Go a single boiler, which is the main difference. The Profitec Go adds PID temperature control. Match the boiler type and control style to how you brew; tiers are price bands — check the current price at the retailer.

Which to choose

Boiler — the deciding spec. The De'Longhi La Specialista Maestro uses a thermoblock / thermocoil and the Profitec Go a single boiler. Heats water on demand through a metal block instead of holding a boiler tank. Fast to ready, compact, common in entry machines; temperature stability is the trade-off. One boiler heats for brewing OR steaming — you switch and wait between. The classic learner's architecture: cheapest path to real espresso, slowest workflow for milk drinks. This drives most of the milk-drink workflow and price difference between them.
Temperature. The Profitec Go has PID temperature control (steadier shot-to-shot consistency); the De'Longhi La Specialista Maestro does not.
Portafilter — accessories don't transfer. The De'Longhi La Specialista Maestro takes a 51mm portafilter and the Profitec Go a 58mm, so tampers, bottomless portafilters and baskets bought for one won't fit the other.
Built-in grinder. The De'Longhi La Specialista Maestro grinds and brews in one machine; with the Profitec Go you add a separate grinder — more counter space and another purchase, but a free choice of grinder and easier to upgrade.
Who each suits. The La Specialista Maestro is also a good fit if you mostly make lattes and cappuccinos; the Go is also a good fit if your counter space is tight.

Which one should you buy?

Pick the De'Longhi La Specialista Maestro if you want one machine on the counter instead of a separate grinder; or if you mostly make lattes and cappuccinos.
Pick the Profitec Go if you would rather choose your own grinder and upgrade it later; or if you want PID temperature control for shot-to-shot consistency; or if your counter space is tight.

Common questions

Do portafilters and baskets fit both the De'Longhi La Specialista Maestro and the Profitec Go?

No. The De'Longhi La Specialista Maestro takes a 51mm portafilter and the Profitec Go a 58mm one, so tampers, bottomless portafilters and baskets bought for one will not fit the other. Budget for accessories separately once you pick.
