To be fair, you can do all of this with LESS too. People seem to think one is better than the other, and I don't think that is true at all. It's more like "what's your stack", because LESS is better for X stack and SASS is better for Y stack. It's like comparing a micro usb charger for an Android phone vs the iPhone charging for an iPhone, it's pointless.
Hey Zach! For sure, that is why I wanted to make sure people didn't think it was a comparison with my first post :)
LESS is great too, I use Sass in my environment but you can do great things with either.
100% agree, once you learn one they're all pretty similar/ have most of the same features. I use Stylus primarily because of the stack I work in. It also seems to have the most compact syntax of the ones I've used.
Seems like there has been a lot of chatter about LESS/Sass lately, here are some light thoughts on why I love Sass.
FYI: This isn't a comparison between LESS and Sass
