NixOS with Hyprland. I don't see myself changing unless something comes along that is just better NixOS. It's perfect for someone like me who loves to tinker but doesn't want to deal with the pain when that tinkering blows up in my face. I know I can set up other distros to have easy rollbacks like NixOS but the fact that it basically forces me to self document the changes I'm making while I'm doing them + the built in rollbacks and atomic upgrades make it essentially impossible for me to break. Even if I want to do something like have the bleeding edge version of one package and the stable version of another that have a shared dependency, it just works.

Getting started was a pain and it feels like I'm learning how to Linux all over again but I'm six or so months in and I'd say it's been worth it.
