But... During the past 5+ years, I rarely ever had a problem with Arch Linux that is not 100% my fault. Manjaro... it had some problem every few days; updates DB would become corrupt, random freezes, login GUI would stop functioning...
I suppose my main complaint was that Manjaro could be great it it simply eased the installation and setup of Arch Linux. I do not understand why they use a completely separate repository. Hopefully they continue to improve!
Manjaro is by far the most stable and problem free. It required a bit of tweaking to set up, and there have been a couple of times when I needed to run a command to reset the package manager to a usable state though.
(To be fair I push the Mint box hardest in terms of installing stuff and tweaking things. Its only been good since I went to XFCE as Cinnamon tended to hog the CPU randomly).
An installer for Arch Linux is something I've been wondering for quite a while and didn't know it already exists :-)
