First impressions between Aurora and NixOS are at least that the last one is more efficient/less bloated, but also requires a lot more work. With Aurorix everything (just, homebrew, starship, nerdfonts) is there, with Asterix you have to tweak config files and rebuild. Ended up adding a lot of cli tools to my configuration.nix, but that defeats the purpose of an immutable core. It's easier to tweak your homebrew and flatpak install files on Aurorix and let them be build into the container (the config files, not the applications).
