I've been running Wayland on a Framework laptop and it just works. Droves my 4K external monitor, quickly switches to single screen, does fractional scaling well, runs all my apps without complaint.

I had an old Chromebook which had Lubuntu on it - screen tearing was driving me crazy so I switched to Wayland and it is buttery smooth. No mean feat given the decrepit hardware.

I'm sure someone will be along to tell me that I'm wrong - but I've yet to experience any downsides, other than people telling me I'm wrong.
