As far as Manjaro being the easier to install, the last time I installed Arch it took the same time or less, and I had to make about 3 decisions in that time. It's straightforward, just lacking the GUIosity. I did it from a bootable image.
I tried Manjaro for a while but didn't like the way it wasn't exactly Arch. Some things wouldn't work. All the good "extras" it comes with are a pacman away, and all the bad ones, well I don't want them. I don't want sponsorship from Microsoft Office on my desktop. Nothing like that.
