Any distro that’s well-documented is not a big deal to install and use. Never understood the big deal people used to make (still do sometimes? though I think it’s mostly ironic now) about Arch. I did my first install Arch when I was kinda a dumbass but I just read the wiki (very thorough, btw, still use that wiki nearly daily) and followed the instructions. Especially with Arch, the wiki is so informative it explains the things you don’t know so you understand what you’re doing even though when I first installed Arch I didn’t know what an fstab file was, what the initramfs was, etc. I’ll disclaim that I’ve not installed Gentoo myself, but I hear from people who have installed it that it’s very well documented, so makes sense that newcomers could install and use it if they’re willing to read and learn.
