A less theoretical advantage is that it can create the exact same environment on both Mac and Linux, and in neither case does it need to replace your primary package manager.
If the whole team is using nix, then the "setup" section of the readme just says "use nix-shell"[1] and that is more than enough for everyone.
[1]: I can't remember if nix-shell is the right command, or not, but in theory nix can create an exact environment on every machine with one command.
