Nix has many more features which are quite nifty, such as atomic upgrades + downgrades, plus being able to install variants of packages. Think GNU stow, but then on steroids.
On the website for Nix there is a link to PhD thesis of the author of Nix, which is well worth a read (the first few chapters are very accessible and clearly explain the problem that Nix tries to solve).
