On non-Linux it should be faster/less overhead; on all platforms I suppose it's just arguably easier/quicker to make changes & 'rebuild', and then the result is that that just is your environment, it's not a container inside it that you have to exec into or run commands through or make your IDE use or whatever.

But mostly it's just two different approaches and people will be happy to argue about why there's is better, or that they don't use either (just the system environment (on a non-NixOS system..) as it were).

I mostly agree, but one big thing missing is Nix is reproducible by default while docker is only repeatable.

Yeah, I was just trying to avoid anything to which you could say 'well I can do that with docker [and appropriate care & attention]'.
