Ok so Arch apparently has an install script that does everything[0]. I tried it the other day and it's pretty flawless, albeit terminal-based so not for everyone I guess.
Pacman is _amazing_. Apt broke dependencies for me every few months & a major version Ubuntu upgrade was always a reformat. Plus, obviously, the Arch wiki is something else. I would go as far as to say you'll have an overall better Linux experience on Arch than Ubuntu and friends, even as a beginner.
