In my experience, Manjaro is a great, user-friendly version of Arch. YMMV, but I highly recommend it!

I used to be a pretty hardcore Manjaro evangelist (and I still recommend it to people who want to quit distro-hopping), but I've been burned a handful of times by it. Arch is obviously a notoriously unstable distro, but Manjaro in particular can lead to some nasty issues. Especially if you're mix-and-matching AUR packages with the Manjaro repository ones; I've had at least 3 or 4 systems get entirely borked because of an untracked dependency or something being too far behind in the Manjaro repo.

I think manjaro suffers breakage too much. These days I tell people to look into endeavour since they still use (mostly) arch repos and thus cause much less breaking with the using AUR packages if you're into those.

Second this!
