I really have no fucking idea about the technicals when it comes to Wayland vs X11, but I do have a little bit of experience now as a user. I've resolved numerous issues instantly (and usually these are issues around running games with wine) by just switching back to X.

I have had good results with Pipewire, especially with respect for easy audio routing, and it's nice not to have to start up jackd just to get that done, but I can't say Wayland has really helped me out yet in a practical way.
