Sass vs. SCSS: Which Syntax is Better?

One thing that always annoyed me with SCSS is having to explicitly tag classes with the `@mixin` keyword before being able to use them elsewhere as a mixin. LESS doesn't make you do that.
Also, one of the most powerful features of Sass today is @extend, which is something that Less definitely does not have: http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#ex...
I can definitely now see that Sass/SCSS is where it's at if one needs to do anything non-trivial with CSS. Guess I should really get back to using it over Less, as the basic syntax is almost identical anyhow.
As far as Sass vs. Less goes, I think it's great that both projects exist and are being improved and adopted at such a rapid pace.
Less certainly borrowed some early ideas from Sass, and in turn SCSS syntax almost certainly exists because of Less.
