I currently run Arch on my main computer (and have for the past few years), Ubuntu on a few others, and have dabbled with some other distros for fun. I'm thinking of giving Debian a shot for my main computer, though.
How would you compare unstable and/or testing to Arch (if you have any experience with it)?
Testing's probably relatively similar to Arch, while I'd liken unstable to the AUR. IME though Arch makes living the rolling-release lifestyle substantially easier -- pinholing certain packages from Unstable can be difficult, whereas yaourt and the like make accessing the AUR easy.
There's also something to be said for mindshare. Ubuntu and its PPA system make it easy for people to build packages, and due to Ubuntu's popularity, there are lots of them. AUR does the same. Finding exotic packages for Debian (eg. Steam) can prove difficult.
