I love wayland. I'm 100% on it since the KDE 6.0 Beta end of 2023. Back then i wanted to try the HDR of my new monitor. I can't remember the last time I had a problem of any kind or thought “That worked under X”.
Multi-Monitor setup with different resolutions and refresh-rates. wayland does not care. it just works. And this is to a big part a gaming machine btw.
they added some nice tools though. e.g. their pacdiff & meld tool eos-pacdiff is pretty nice. then there is a kernel manager and a pretty clever update-script / wrapper around pacman and yay (eos-update). saying it is just Arch + GUI is selling it a bit short imho.
