• I daily drive Plasma 6 Wayland on Archlinux based distro (EndeavourOS). Its the most stable KDE I have ever used. Before that I was using since Plasma 5 X11 on same distro and switched to Wayland when 6 became available. Unless you have some issues that are specific to your setup, it works surprisingly well. I even use an auto tiler addon and added a second monitor (ok the monitor is since today :D).

    All in all, its stable after the 2 big updates that focused on stability since 6 launched.
