It has been pretty solid, like 23.10. Ubuntu's implementation of gnome is very nice and wayland is working very well with my 7800XT card. No complaints at all.
I did, for fun, enable the extension "Burn My Windows" which allows you to enable a variety of special effects upon window creation and destruction. They are very efficient, being native shaders. They are pretty cool too. :D
I watched an interesting KDE6 review the other day. I feel like I need to experience it, install OpenSUSE or something and try it out, despite how stable Ubuntu has been. The only problem is I never really LOVED KDE and, while they have actually made some improvements around the decoration aspects that always bothered me, I am hesitant to try it. The reviewer said "if you didn't like KDE before, you probably won't like it now" despite the improvements.
So anyway...
