It should be pointed out that you can install the nix package manager in Arch (or whatever other Linux, or macOS, etc.), so you can try out nix's declarative package management without actually switching to NixOS.
I tried this on my previous laptop and ran into a number of issues once I tried to install anything with a GUI. It's fine for shells and CLI tools though. I migrated some configs over to a Nix configs under Arch, and while it was a pain to initially set up NixOS (unfamilarity), it's a lot easier doing everything else now.
