Yeah, Gnome consolidates feature changes into major releases every six months, so it aligns well with fixed release distros like Ubuntu and Fedora that have release cycles that are aligned with Gnome's.

KDE drops a new point release with new features ~ every four months, and has a more flexible release schedule, so it is just to just get the changes when they are released.

I'm currently running KDE on NixOS unstable which is great, but if I weren't doing that I'd still be on OpenSUSE Tumbleweed.
