Yeah I’m more concerned about whether it has what I actually want. Which when I used it over a year ago it was missing tons of programs I use (both first and third party channels) and Nix was not. Although it’s nice to see that Niri and Helix are packaged now and their Rust packaging improvements. Other aspect is the flake ecosystem, where Nix has flakes for things like styling, security hardening, etc whereas Guix didn’t seem to have a flake-like implementation at all. Although at least it’s an alternative if systemd really goes to shit.
