Well for almost all my GNU/Linux systems (all with KDE Plasma 6 now) with AMD and intel I would say yes, it is even smoother and faster and has lower latency than with X11, unlike the results in the articles. The only thing I really really miss in Wayland is session restore. I sure hope this gets fixed soon. In KDE Plasma yes it is partialy done but still far from what is there in X11. But yeah Nvidia graphics on one of my machines is a big pain in Wayland even ore so than in X11. So yeah not buying that one in the future for sure, just not worth all the problems it causes.

Used it for a couple of months and actually had better perf and responsiveness than X11 on my Lenovo X1 Carbon with Intel graphics. For me, I eventually got too much of a wrist pain from my mouse scroll wheel scrolling incredibly slow. On X11 it is fixable using the imwheel utility, but for Wayland i concluded from several GitHub issue threads that nobody can agree on where the fix should be done. (This was a year ago or so, so don’t know if it has been fixed since).
