I have been a KDE user since 2010. I've started this habit a few years ago that every time I upgrade my desktop distro's release, which is twice per year (first Kubuntu, now NixOS), I try out the wayland mode for a while, until I find the bugs to be too annoying. A few years ago I switched back after a couple of hours. The last time I tried I remained there for 3 months. So yes, a lot has improved, but I'm still back on X11.
I'd also confirm this. Gnome started out ahead by virtue of being the target or idealization of most of Wayland's features, but it's stagnated. Nothing is ever improved and they refuse to fix the technical problems holding them back, like the lack of I/O being separated from drawing in Mutter. They claimed to have improved it several times, but it's just as bad as ever. Either they're hesitant, or they just don't have the time and resources to break and rebuild it properly.
Meanwhile, KDE/Plasma's kwin finally stepped past them. And there's also the kwinft project that's rebasing kwin idiomatically as a wlroots compositor.
We may finally get full Wayland adoption, but I don't think Gnome is going to be prominent in it anymore.
This makes me sad because I really like how Gnome looks like, but Gnome developers don't seem to care as much about Wayland stuff.
