My experience with Fedora KDE has been very positive with the caveat that the default package selection has been a bit bloated and it’s not just my impression. github.com/edythawne/KDE-Minimal-Install exists for a reason. Stability-wise the experience is good, the liberal update cycle is nice.
Personally, I did not find Kinoite so appealing but maybe things changed since then (I think I tried it out a year or so ago).
