Well, if I look at GitHub stars (not the best metric, but still), then less.js has about 3x more stars than sass.

I like node-sass as well. It would be great to have something similar and popular enough for LESS. Official Javascript-based compiler isn't sometimes fast enough.

Yes, Gulp is great in many ways and Phở uses it as a task runner.
