I think much of the valid "us vs them" arguments came in the pre-SCSS days. Back then SASS was NOT a superset of css, while LESS was. So choosing between them could lead to very different codebases / workflows. These days they are both supersets (or rather, SCSS is a superset, you know what I mean), and they have many of the same options available, so IMHO the differences are trivial.
