Honestly, it’s really not that special. Only reason I would ever use Arch is the AUR (which nixpkgs are a lot bigger than) and its absolutely great wiki (which you can use as a guide no matter your distro.). The reason there is a really small elitist community among the Arch Linux users is the knowledge you need to know to install it, and its illusion of minimalism.
