Yeah this is accurate. I've installed arch several times over the last decade and can mostly do it by heart without consulting the docs... but the amount of possible choices is just crazy and keeps going up.

Also, things like disk encryption is easy to get wrong, leading to another boot from the usb/mount everything/fix loop.

Nix has a graphical installer, which makes most of these choices for you. Different projects have added similar installers on top of Arch too, making its indtallation as easy.

And in actual use Arch is much simpler.
