I realize you’ve already made your switch, but I wanted to toss in my 2 cents. I had a very similar, though shorter term experience with Arch, and I still love it dearly, but over time some jank began to creep in around the edges. The time came to make some sort of change when I finally decided to wipe the windows boot drive I had in the system. I took the opportunity to upgrade the m.2 ssd and decided on NixOS for a handful of reasons, and it’s honestly been super refreshing. I feel even more in control of the stability of my system than any OS I’ve used before. If something is going wrong, it is most likely something I did in my config, or the config isn’t even valid and the system tells me exactly what is wrong before I even get to a point where I’m trying to boot into a broken system. I ignored a lot of the online recommendations to use flakes and home manager and whatever. Just a single text file with all the details of my system in it. I find it incredibly digestible compared to tracking down issues with Arch.
Anyway, I also have a Bazzite system, and like it. Sounds like you’ve found a nice new home!
Been meaning to swap to Niri, but I’m dreading trying to “convert” my Hyprland config to it.
