If I were starting today I'd definitely choose the Core One over the P1S (thanks to this rug pull). It's vastly more expensive, and the MMU isn't worth it from what I've heard, and the build volume is significantly smaller, but I don't think I'd go with Bambu after this week.

I wouldn't buy any new Prusa printer until it's been in the wild at least a year, they tend to be very buggy at launch.

They also have no multimaterial support at launch, the MMU3 will not work with the Core One until they release an update, which they've not yet given a timeline for.
