Unless you're heavily into using Compass or Foundation I don't see any major reasons to favor it over Less as far as features go. Both are really powerful. One advantage of using Less is the existence of (php) libs so you can compile on the server. If you're developing for WordPress users for example you can expose some variables (ie colour scheme) and recompile stylesheets with minimal fuss.
