> I have not tried installing/using NixOS It's like Nix-Darwin but without any setup issues, spared from breakage related to OS upgrades, but also with fewer escape hatches (Flatpak is the main easy one it does provide, also steam-run) for app installation. If you do enjoy Nix-Darwin once you get it going and you at least somewhat enjoy Linux desktops, you'd probably enjoy it as a daily driver. I would say that for users new to the Nix ecosystem, NixOS on a spare machine is the most gentle and pleasant way to introduce the module system and declarative Nix config. It tends to be smoother than Home Manager or Nix-Darwin, and it's a lot more complete than either, both because it has more users. But a spare machine is a good choice for those who aren't yet sure that they like or care about Nix, because if something is missing or non-obvious, the only way out is through— you have to dive deep. NixOS is so mature these days compared to when I first picked it up, though. Packaging work just to get by on the day-to-day is way more rare, and there are a lot more examples around. A Linux hobbyist who is prepared to struggle a bit can definitely just dive right in and have a good time, for sure.
