I'll start, I use Linux Mint on my laptop that I use for work daily. It uses the latest Xanmod linux kernel and flatpaks for apps with GNU Guix providing everything else.
Debian 11 on my 10 year old desktop, Debian 12 on my micro form factor desktop that I've recently bought, Archlabs on some 15 year old laptop.
Edit: Wtf, it turns out Archlabs has been discontinued. This laptop is cursed. First Crunchbang, now Archlabs, I swear this laptop just attracts distros that don't last for whatever reason.
