Primary-source rechecks: Breville Dual Boiler (BES920): portafilter fitment

Which to choose

Boiler — the deciding spec. The Breville Dual Boiler (BES920) uses a dual boiler and the Lelit Grace 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.
Pre-infusion. Only the Breville Dual Boiler (BES920) pre-infuses (gentler shot start, better extraction on lighter roasts).
Portafilter — accessories don't transfer. The Breville Dual Boiler (BES920) takes a 58mm portafilter and the Lelit Grace a 57mm, so tampers, bottomless portafilters and baskets bought for one won't fit the other.
Who each suits. The Dual Boiler (BES920) is also a good fit if you mostly make lattes and cappuccinos; the Grace is also a good fit if this is your first espresso machine.

Which one should you buy?

Pick the Breville Dual Boiler (BES920) if you make milk drinks and do not want to wait between pulling the shot and steaming; or if you want pre-infusion for a gentler shot start on lighter roasts; or if you mostly make lattes and cappuccinos.
Pick the Lelit Grace if this is your first espresso machine.

Common questions

Which is better for lattes and cappuccinos, the Breville Dual Boiler (BES920) or the Lelit Grace?

The Breville Dual Boiler (BES920). Its dual boiler brews and steams at the same time, while the Lelit Grace uses a single boiler and makes you switch and wait between the shot and the milk. For milk-heavy drinks that wait is the difference you feel every morning.

Do portafilters and baskets fit both the Breville Dual Boiler (BES920) and the Lelit Grace?

No. The Breville Dual Boiler (BES920) takes a 58mm portafilter and the Lelit Grace a 57mm 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 Lelit Grace. Of the two, it is the one that is easy to learn and forgiving while you find your feet. The Breville Dual Boiler (BES920) makes more sense if you mostly make lattes and cappuccinos or you want to fine-tune every shot.
