Sass versus LESS

Quoting, "One of the hot new trends in web design is CSS pre-processed languages and there’s two big ones vying for your attention—LESS and Sass. LESS and Sass are both ways of writing CSS code with a syntax that allows you to use features not yet available with Cascading Style Sheets ( CSS ), such as variables, nesting, conditionals, and more. 
 Pre-processed CSS languages add features to CSS that aren’t there yet—like variables, conditionals, and functions. They’re called pre-processed, because their final step is a processing, also called compiling, that converts the pre-processed language to regular CSS . In a nutshell, what you use on your site ends up being plain vanilla CSS , but comes as a result of processing the LESS , Sass, or other pre-processed language files you create." via Lynda.com blog
