Which to choose
- Price tier — the headline difference. The Ascaso Steel Duo PID sits a tier up (prosumer) from the ECM Puristika (mid-range) — you pay more for the spec advantages below. Tiers are price bands; confirm the live price at the retailer.
- Boiler — the deciding spec. The Ascaso Steel Duo PID uses a dual boiler and the ECM Puristika a single boiler. Separate boilers for brew and steam, each independently temperature-controlled. The most stable, most flexible architecture — and the most expensive. 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 Ascaso Steel Duo PID has PID temperature control (steadier shot-to-shot consistency); the ECM Puristika does not.
- Reach. The Steel Duo PID also fits latte & cappuccino.
