You get 3-phase in the US if you live in a large apartment complex. Especially if it has an elevator. Since this combines to get 208V, the math works out to making your 240V stove only 75% of what it should be.
For residential use, split phase is fine. We just run the two legs to get 240V on the specific things that need it. That’s generally electric stoves, water heaters, AC unit, electric dryer, and more recently, EV chargers. 3-phase is great when you’re driving something that spins with a high draw, and of those, only the AC unit does that (electric dryers spend most of their electricity heating, not spinning).
