I never recommend Manjaro, even for experienced users. Multiple times, they’ve let their ssl certificats expire, and renewing those has been easy to automate for a number of years at this point. There have been a number of cases where they ship work-in-progress versions of software as part of their default install, and there was an open letter posted calling this out: https://dont-ship.it
So in my opinion, Manjaro leaves much to be desired from a project governance standpoint.
Now, using an Arch-based distro that does the install process for you doesn’t absolve you from learning what it takes to maintain an Arch install; at some point, something will crop-up that requires manual intervention to get back up & running again after an update.
If that is what you’re looking for, I suggest EndeavourOS.
I’ve been using wayblue on my own desktop. They have sane defaults & very pleasant theme. They do a good job keeping their image up to date & enable auto-updating from the get-go.
