I'd say Nix is 95% wonderful, 5% very painful.

If you're trying to do something with Nix and it works, neat.

If you're trying to do something and can't get it to work, you'll have a very difficult time. (It demands a depth of understanding, and Nix is a bit weird).

Hopefully in future, "documentation", "blogposts from randoms", etc. help alleviate that pain as more people use it.
