If most of what you make has milk in it, one specification decides the machine — and it is not the one on the front of the box.
For milk drinks the steam system is the machine. A dedicated steam boiler that lets you brew and steam simultaneously — as on the Breville Dual Boiler or Lelit MaraX — changes the experience more than any other feature. Below that budget, an automatic wand like the Bambino Plus produces good microfoam for one or two drinks.

Ranked on our milk-capability rating, derived from steam architecture: a dedicated steam boiler counts for most, simultaneous brewing and steaming next, a real steam wand next, with a penalty for assisted Panarello-style wands that aerate rather than texture.
Milk texturing needs dry, powerful steam and enough of it to finish the jug before the milk overheats. That comes from thermal mass, which means a boiler.
A machine with a dedicated steam boiler — the Breville Dual Boiler has a 950ml one — has steam available continuously and brews at the same time. A
heat exchanger like the Lelit MaraX draws brew water through a 1.8L steam boiler, giving the same simultaneity from one vessel.
A shared circuit — every thermoblock machine, and every single boiler — has to switch modes. That is a wait, and it is why milk-heavy households outgrow single boilers first.
The Bambino Plus does something none of the prosumer machines do: it textures the milk without you. Three temperature settings, three texture settings, walk away. For one or two drinks that is a genuinely better outcome than most people achieve by hand.
The Barista Touch Impress and Oracle Jet extend that to alternative milks, which most automatic wands handle poorly.
So there are two routes: buy steam capacity and learn to use it, or buy automation and accept its limits. The first scales to four drinks; the second does not.
Panarello-style assisted wands, which is what you get on the Stilosa and Dedica. They aerate milk reliably. They produce bubbles rather than the dense microfoam a flat white needs, and no technique gets around the design.
Chosen against the criteria above. Every specification links to its source.
Two boilers, PID on both, a heated group head and a 58mm portafilter. It brews and steams at the same time, which is the structural difference that separates it from everything cheaper Breville makes.
A Bambino with the milk step automated. You set temperature and texture, it steams while you do something else, and it is one of the few machines under $500 that will reliably produce microfoam without practice.
A heat exchanger that behaves itself. The MaraX manages brew temperature electronically rather than leaving you to flush and guess, which is what makes it the usual recommendation for a first prosumer machine.

Introducing air briefly at the start and then spinning the milk so the bubbles break down into a uniform texture. An assisted -- Panarello -- wand injects air throughout which is why it makes foam rather than microfoam.
Only if you make several drinks in a row. Making one flat white the wait on a single boiler is about a minute. Making four it is the whole morning.
