I’ve been using arch for a while now and I always used Flatpaks for proprietary software that might do some creepy removed because Flatpaks are supposed to be sandboxed (e.g. Steam). And Flatpaks always worked flawlessly OOTB for me. AUR for things I trust. I’ve read on the internet how people prefer AUR over Flatpaks. Why? And how do y’all cope with waiting for all the AUR installed packages to rebuild after every update? Alacritty takes ages to build for me. Which is why I only update the AUR installed and built applications every 2 weeks.
I use flatpak steam and flatseal to remove user home permissions so games don’t see my files.
I’d prefer to use Nix derivations and firejail but I couldn’t get it working last time I tried.
My preference for nix expressions to flatpaks is for better reproducibility guarantees, easier introspection, easier debugging, and less duplication.
