I do try to shop around every few years, but return to Gnome. KDE is perpetually never quite right. Visual clutter, forcing desktop metaphors like Activities on me, and poor integration (read: different toolkit) with the things I actually use.
I agree, I should leave. But doing that is even more change. At some point I just need to get some work done. I'll moan and groan and maybe one day Gnome governance will stop individuals vandalising the project's applications without community buy-in.
