If the issue is a breaker flip, then you only need to be on different breakers, right? Phase is irrelevant in that case
Right, because the main breaker would be 2 pole (or at the very least handle tied).

Generally, yes, but there are some exceptions like different breakers on a shared neutral, which may be tied so that both circuits break.
I don't have a power outage more than once a year, but we manage to blow a breaker more than a few times a decade (vacuum + water boiler was one).
