I don't think I'd recommend Manjaro as a first distro either. Mint was the first distro I used 8-hrs a day; though it's conservative update policy was eventually the prompt to move.
With a year or two of experience in the bag jumping over to Manjaro worked very well for me; when I started wanting the "extra" power while still having some cuddly UI around it. The AUR functionality is particularly useful.
I still can't run all of my hardware in Manjaro; and have to keep a copy of CentOS7 around on a spare partition to push an LTO drive around in the absence of Windows.
