Linux

I personally love Wayland for my system. I use Sway for mine and with support for VRR with my monitor, a lot of the vsync problems people talk about goes away (at least for me). I will say, some things that rely on Xorg screen sharing (Like Discord) will only share Xwayland windows. This is fixed in most applications, but not all. Also screen recording in general is a bit lacking. My main pro for Wayland is I use multiple monitors, and unlike Xorg which caps the refresh rate for the full desktop to the lowest (which for me is 75hz), Wayland allows different refresh rates per monitor, which means if I drag a vsync game over to a different monitor, the fps cap changes.

Wayland is also vastly improved by moving over to PipeWire instead of Pulseaudio. I've never had a singular problem with PipeWire and it's drop-in pretty much. I recommend that as well. PipeWire is compatible with applications that use PulseAudio so you shouldn't even notice a difference at worst, and will notice an improvement in sound latency most likely.

I think the main drawback about Waypand right now is people have VASTLY different experiences. Which is why I say just try it out. Most big DEs like KDE and GNOME have Wayland sessions that you can choose if you just install the wayland parts. Worst case scenario you go "This sucks" and go back. Wayland is only getting better, though, and I find that a lot of the problems I had even just 6 months ago are pretty much gone. Check in often and just keep your Xorg stuff laying around. That's the beauty of Linux.
