Interesting.
Normally, I like Debian as it is more stable and has more easily available support. What most people would atomically give you in commands. Arch isn't as common commands found when looking for general support. I would advise a Debian based Linux to start however, once you are more comfortable with Linux and willing to and know how to find more support and importantly understand if you are looking at a Debian command vs, Fedora vs Arch in general and you want more bleeding edge and "rolling updates" and most of all more control, this might be something you would want to look at.
