For me the best thing about scss is the ability to nest selectors. This makes your code a lot easier to read and more organized. Of course having functions, mixins, extends is also nice.
Saying scss is pointless because it outputs regular css is the same as saying that es6 is pointless because it can be represented as regular es5.
>...es6 is pointless because it can be represented as regular es5.
Let's be reasonable, that's more like comparing CSS 2 to CSS 3. :P
Everything I've read and discussed with others in the industry, SCSS seems to be useful for far large projects with many designers and programmers stepping over eachother. I work for a smaller company, and we build very clean CSS, and would not benefit at all from SCSS.
Recently a friend at another medium sized company switched to SCSS "because". Seriously, it was one designer that liked one feature from some library that required some build tool that required SCSS... So they all have to learn SCSS now. No other reason.
Maybe I am stupid here, but doesn't SCSS just render out to CSS?
