The fact that it comes setup with cocky, ob-keys (hot keys for web, file manager, ...), openbox was nice. Way back when I gave it a try and moved on to archbang then arch. It is just nice that it provides a certain try of environment out of the box. I'm sure one could make a post install script to do the same with arch or Debian but that takes time. Sometimes I just want to get to work and install my other software that I need.
