I've used scss and less and I prefer SCSS. When I first started using less I found the javascript parser missing some functionality that was in the full ruby gem. Also, since I use django, I found integrating with scss much easier, especially with pyscss. I find that scss provides a level of abstraction that I am comfortable with. Because of pyscss I can run it from the command line and figure out exactly what is going on pretty easily. With compass I find that I write much cleaner css code. But the big win is being able to nest my css. Nesting CSS brings it much closer to the HTML that you are styling. In my mind this is the huge win.
