I’m not familiar with ports, does it provide an easy way to install packages of a particular version? Is it OpenBSD only, or just a system of installing things?

I’ve got no dog in the race as of yet, I’ve bounced off of nixos a few times because of the general lack of consistency from one package to the next in terms of configuration options made available in the Nix language.

Genuinely curious about how it compares. The nix package manager seems fairly promising, even on non-Nix systems, if I could ever convince myself I needed it
