For me, there are three main reasons: * Customizability. It's very easy to build a system just the way I want it. * Rolling release. There are no releases every six months, but when a new version of a software is released, I get it after a short testing period. * Package availability. Everything I need is either in the repositories or easily buildable from AUR. (Using simple recipes called PKGBUILDs). BUT: This is only great, if you know your way around Linux - I can install and configure Arch in less than 2 hours, but my notebook for instance uses the same install for about 2 years now. The good wiki helps to gain this knowledge, but it's still very unfamiliar for most people.
