Which to choose

Price tier — the headline difference. The Breville Dual Boiler (BES920) sits a tier up (mid-range) from the Breville Barista Express Impress (entry) — you pay more for the spec advantages below. Tiers are price bands; confirm the live price at the retailer.
Boiler — the deciding spec. The Breville Barista Express Impress uses a thermoblock / thermocoil and the Breville Dual Boiler (BES920) a dual 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. Separate boilers for brew and steam, each independently temperature-controlled. The most stable, most flexible architecture — and the most expensive. This drives most of the milk-drink workflow and price difference between them.
Portafilter — accessories don't transfer. The Breville Barista Express Impress takes a 54mm portafilter and the Breville Dual Boiler (BES920) a 58mm, so tampers, bottomless portafilters and baskets bought for one won't fit the other.
Built-in grinder. The Breville Barista Express Impress grinds and brews in one machine; with the Breville Dual Boiler (BES920) 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 Barista Express Impress is also a good fit if this is your first espresso machine; the Dual Boiler (BES920) is also a good fit if you want to fine-tune every shot.

Which one should you buy?

Pick the Breville Barista Express Impress if you want one machine on the counter instead of a separate grinder; or if you want the lower price band (entry rather than mid-range); or if this is your first espresso machine.
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 would rather choose your own grinder and upgrade it later; or if you want to fine-tune every shot.

Common questions

Which is better for lattes and cappuccinos, the Breville Barista Express Impress or the Breville Dual Boiler (BES920)?

The Breville Dual Boiler (BES920). Its dual boiler brews and steams at the same time, while the Breville Barista Express Impress uses a thermoblock / thermocoil 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 Barista Express Impress and the Breville Dual Boiler (BES920)?

No. The Breville Barista Express Impress takes a 54mm portafilter and the Breville Dual Boiler (BES920) a 58mm one, so tampers, bottomless portafilters and baskets bought for one will not fit the other. Budget for accessories separately once you pick.

Is the Breville Dual Boiler (BES920) worth the step up from the Breville Barista Express Impress?

Stepping up from entry to mid-range buys you a dual boiler instead of a thermoblock / thermocoil. Worth it if you brew milk drinks daily or chase consistency; not if you mostly pull straight espresso. Tiers are price bands — confirm the live price at the retailer before deciding.

Which is the better first espresso machine?

The Breville Barista Express Impress. 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.
