I’d say it’s definitely worth it. I don’t actually use nixos itself, but I do use nix a lot. I have everything I need for work in a home manager configuration, so I can literally just install nix and load up my config and have all programs and configuration of said programs installed and ready to go (on any UNIX system). I started doing this since changing jobs means a new machine, and I got really tired of all of the inconsistencies between machines when bringing over my dotfiles, and having to install a bunch of packages I use every time I changed jobs.

I do want to make the switch from Arch to nixos on my personal machine eventually too, but I hardly spend any time on computers outside of work these days, unfortunately. But the great thing is that my home manager configuration can pretty easily slide right into a nixos configuration, which is what many people do.
