I am enjoying setting up and using my new Debian 11 (Stable) system on my HP Envy laptop. It's this laptop's second time running Debian, and things have been smooth and predictable.
One of the reasons I paused on NixOS was the /nix/store size. My VM filled up pretty quickly. Not ruling it out forever but passing for now. https://www.reddit.com/r/NixOS/comments/x1sfff/nixstore/
Both Debian and Fedora are my home distros. I go back and forth with them. When I got my first SSD, I put Debian on it. When I got my second SSD, I put Fedora Silverblue on it. Now I've gone back to Debian on the newer SSD. My old iMac has run Debian for a long time.
