I used to recommend Manjaro to people as an alternative to Arch that's a bit friendlier, but I stopped after trying to debug an issue and realizing that they have overcomplicated a lot of things (kernel management in particular bugs me in Manjaro.)
Arch now has some kind of installer, so I guess that's an improvement. Though, I really wish Valve could package something like SteamOS 3 for regular desktops. I'm aware of multiple projects that do similar things, but the execution on Deck is quite good. The "immutable" concept is certainly going to be an important part of Linux on desktops in the future, probably in different forms.
