Which to choose

Boiler — the deciding spec. The De'Longhi La Specialista Maestro uses a thermoblock / thermocoil and the ECM Classika PID 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 ECM Classika PID has PID temperature control (steadier shot-to-shot consistency); the De'Longhi La Specialista Maestro does not.
Pre-infusion. Only the De'Longhi La Specialista Maestro pre-infuses (gentler shot start, better extraction on lighter roasts).
Portafilter — accessories don't transfer. The De'Longhi La Specialista Maestro takes a 51mm portafilter and the ECM Classika PID 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 ECM Classika PID 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 this is your first espresso machine or you mostly make lattes and cappuccinos; the Classika PID 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 want pre-infusion for a gentler shot start on lighter roasts; or if this is your first espresso machine or you mostly make lattes and cappuccinos.
Pick the ECM Classika PID 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 ECM Classika PID?

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

Which is the better first espresso machine?

The De'Longhi La Specialista Maestro. Of the two, it is the one that is easy to learn and forgiving while you find your feet. The ECM Classika PID makes more sense if you want to fine-tune every shot or your counter space is tight.
