Yes, I am amazed that quite a few people in this thread are saying they ‘had to completely reinstall the os’ and that it broke everything after not much time. As long as one doesn’t rely on the AUR for system critical packages or much in generel, it is incredibly hard to break an Arch system (Manjaro and other Arch-based distros don’t count). This is due in part to Arch being quite reproducible but it also having very good maintainership.
It doesn’t hurt to apply new package configs by going through pacdiff once in a while though.

Edit: Typo

I see no one has mentioned Bedrock Linux yet. Not sure though how others would rate its ‘obscurity’ though. It’s definitely a standout among distros.

KDE for its Wayland performance and features and occasionally I switch to hyprland if I need a more focused work environment.
In the past I used Cinnamon but it became ever more buggier on Arch and due to lack of Wayland support still it was a dead end anyway.
