How these were chosen
Machines with an integrated grinder, scored on our full fit ratings with the built-in grinder counted as a stand-in grinder: maximally convenient, taking no extra counter, and unable to be upgraded, with its control rating set by how many grind settings it actually offers. That is the same treatment our setup builder uses, so an all-in-one competes fairly against a machine-plus-grinder pair rather than losing for having fewer parts.
What the grind settings tell you
This is the number to read, and it is the one most reviews skip.
A standalone DF54 at around $265 is stepless — effectively unlimited positions. That is the gap you are accepting in exchange for one appliance.
Which to choose
The Barista Pro is the balance point: thirty settings, ThermoJet heating for a three-second start, and an interface that shows you what is happening. Under $1,000 it is the one we would buy.
The Barista Express is the same idea for less money, with a PID thermocoil instead of ThermoJet — better temperature control, a much longer warm-up.
The Oracle Jet is the only all-in-one here with a 58mm portafilter and 45 settings, plus hands-free milk. It also costs as much as a dual boiler and a very good standalone grinder, which is the comparison to make before buying it.
The one honest warning
You cannot upgrade the grinder. Not a little — at all. If you are the kind of person who reads a page like this, there is a real chance that in two years the built-in burrs will be the part of the setup you want to change, and the only way to change them will be to sell the machine.
If that sounds like you, read integrated grinder or separate before deciding.
