SharePlay to Mac is utterly broken, see my other comment.
Other than that, it seems more stable and faster than Big Sur, and that's without a clean install. Notes used to take 4 bounces to open on M1, now opens instantly. Haven't seen any crashing. No broken features that aren't brand new. I've only found one bug: Safari reopens private windows even if you turn that off. But no problem if you don't use Safari.
