> "Do you use presentational CSS classes in markup, or do you fully utilize LESS/SASS?"
Are those even exclusive?
One of the projects I work with uses Ace “responsive admin template” (paid theme from Wrapbootstrap). In its styles, declared variables and nesting are used unpredictably, as is indentation and other whitespace, which leads to awful readability and flexibility. It does utilize LESS, but it also uses presentational classes (least of its problems).
Pure well-structured CSS can be much better. LESS offers some useful possibilities, but also a lot of new ways to shoot yourself in the foot.
My point is—what OP wants (I guess it's readable, elegant, maintainable code) depends more on coding standards than tools used.
