The Express Impress is integrated and assistive: a built-in grinder, intelligent dosing to ~±0.5g, and the Impress assisted tamp, all on a 54mm portafilter with a single thermocoil and a manual wand. The Dual Boiler is grinder-less but far more capable: two PID boilers plus a heated group hold temperature to ±2°F and allow simultaneous brewing and steaming with no wait, with programmable pre-infusion up to 60 seconds and a commercial 58mm group.
The Impress removes beginner variables in one box; the Dual Boiler removes thermal and workflow limitations for an enthusiast. If you value never buying a separate grinder and getting repeatable shots with no skill, the Impress wins; if you value simultaneous brew-and-steam, deep dialing, and the 58mm ecosystem, the Dual Boiler does.
The Impress's single thermocoil forces a brew-to-steam wait and its 54mm format limits accessories; the Dual Boiler needs a separate grinder (adding cost) but offers prosumer headroom the Impress can't.
Buy the Barista Express Impress ($800) for a complete, assisted, easy grind-to-cup machine. Buy the Breville Dual Boiler ($1,600) for simultaneous brew-and-steam and serious extraction control, with your own grinder.
