Chris Coyier wrote a nice article detailing some of the details http://css-tricks.com/sass-vs-less/

The single biggest difference is in available style libraries in my opinion. I could probably never use Less because my workflow has become so heavily intertwined with Bourbon, Susy, and Compass.

This article is sweet! Sass is definitely looking more and more appealing.

Thanks for sharing!
