Use arch if you want more compatibility. Debian is stable but it also means their official package repository will lag behind some feature that is present on the bleeding edge. IMHO, stability is good if you are already familiar with Linux AND want it that way, but with windows compatibility in its current state (emphasis there), it is better to go bleeding edge for new users since you are transitioning anyway, you might as well try the latest feature available. Also, the biggest game changer, valve and steam, is basing their OS on Arch.
