I'm an Arch user who come from Manjaro. Arch Linux seems kinda scary beast to begin with, especially when you are newbie in the Linux world.
There is a huge difference between having good GUI for both installation and management (Manjaro) and having text-based Wiki for everything (Arch). I did not need to read anything when I install Manjaro, though it it true that I learned a lot after I switched to Arch. Not everyone want to experience pain of learning at the beginning. Also, Manjaro provides GUI that let you switch different versions of Kernel and GPU drivers with a few click.
Lastly Manjaro has complete Desktop Environments for Gnome, KDE, and Xfce. These DEs have pretty cool tricks and packages alongside with their default packages. They are something hard to figure out when you use Arch.
