I've been using Arch as my primary OS for about 1.5 years and have no inclination whatsoever to move away from it. Like many people, I previously used Ubuntu, but grew fed up with the focus of their development efforts on areas which I considered to be inconsequential. Seeing the direction that Ubuntu has taken since then, I'm glad I made that decision when I did. For me, the best thing about Arch is simply how flexible it is. It feels more like a toolkit for building your own custom OS than anything else. That's obviously not for everyone, but it's definitely for me. I've got a trimmed-down, keyboard-driven, and CLI-focused interface that would not appeal to the average user, but it was fun to configure and I've learned a ton from the experience. My computer behaves exactly the way I want it to, with virtually no compromises, and that was a far easier goal to attain with Arch than with any other system I've tried. Also, as a bonus for anyone interested in Haskell, there's a rather large Haskell community within the Arch community. In fact, there's a vast user-maintained repository of Haskell packages built for Arch (a large portion of the packages available from Hackage) which you can enable just by adding a line to /etc/pacman.d/mirrorlist. For anyone who likes to tweak and tinker, and who loves having full control over their computing experience, I highly recommend it.
