Well, in some contexts, yes, although to be honest I don't use Vagrant myself, so it's hard for me to compare use-cases. I see Nix as much-needed conceptual competition in the ongoing package-manager vs devops-deployment dogfight, to both package managers (rpm, yum, zypper, dpkg, apt-get...) and devops tools like Chef, Ansible, Salt, and Puppet. Nix is both, and does cool things like try to resolve a binary that will work on your architecture on the fly at runtime, and compiling one if it can't find one in the repo. It's just... better. Go try it.
