I might recommend something Arch-based that’s opinionated and feature-complete, like Manjaro or Garuda, but I’d recommend pure Arch to the same people who would equally enjoy NixOS.

I’ve seen it a handful of times and find it pretty wild. It’s certainly not some widespread thing.

I do agree with the point, though.

Its a good way to learn how different parts of Linux work

After you install arch a couple times you won’t be making posts asking why your grub is broken, youll already k ow how to fix it.
