Which to choose

Price tier — the headline difference. The Breville Oracle Jet sits a tier up (prosumer) from the Breville Dual Boiler (BES920) (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 Breville Dual Boiler (BES920) uses a dual boiler and the Breville Oracle Jet a thermoblock / thermocoil. Separate boilers for brew and steam, each independently temperature-controlled. The most stable, most flexible architecture — and the most expensive. 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. This drives most of the milk-drink workflow and price difference between them.
Portafilter — accessories don't transfer. The Breville Dual Boiler (BES920) takes a 58mm portafilter and the Breville Oracle Jet a 54mm, so tampers, bottomless portafilters and baskets bought for one won't fit the other.
Built-in grinder. The Breville Oracle Jet 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 Dual Boiler (BES920) is also a good fit if you want to fine-tune every shot; the Oracle Jet is also a good fit if your counter space is tight.

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 would rather choose your own grinder and upgrade it later; or if you want the lower price band (mid-range rather than prosumer).
Pick the Breville Oracle Jet if you want one machine on the counter instead of a separate grinder; or if your counter space is tight.

Common questions

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

The Breville Dual Boiler (BES920). Its dual boiler brews and steams at the same time, while the Breville Oracle Jet 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 Dual Boiler (BES920) and the Breville Oracle Jet?

No. The Breville Dual Boiler (BES920) takes a 58mm portafilter and the Breville Oracle Jet a 54mm 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 Oracle Jet worth the step up from the Breville Dual Boiler (BES920)?

Stepping up from mid-range to prosumer buys you a thermoblock / thermocoil instead of a dual boiler, a built-in grinder. 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.
