I agree 100% with this article. However I switched to NixOS several years ago. On the axes I most care about, NixOS is better than Gentoo. In particular, managing configurations in NixOS is really a breeze. No more merging diffs of random files in /etc. On one hand, you could say that Nix has more magic than Gentoo, but on the other hand, the online nix option search links directly to the source code implementing the option. Gentoo wins on documentation and supporting more than one init system. It probably also wins on security; I haven't dug recently, but NixOS doesn't have a great story for e.g. Mandatory Access Control. Also the nix store is world-readable, so it is much easier than it should be to accidentally spill your secrets to the entire system.
