I’m currently on Neon on the desktop (and macOS on the mac). On the servers it nearly all debian and a couple of BSDs
Over the last almost 25 years i’ve almost exclusively ran KDE when not being stuck with windows (for various reasons). Ive heard good things about Arch, but I’m getting far too old to be bothered with a semi-complex install (yes I have run Gentoo for several years, so I think it is an age thing).
