I gave it a shot and now I like it. I don't have to add classes to my HTML and separate my CSS. I find it more maintainable. The built-in config and colors are also quite good.
I nearly always use the built-in config. Though oddly enough, I don't like the new colors (>=3.0 I think), because there's just too many of them now. What I appreciated was the restricted option set; now it just feels like I need to worry about design decisions, which is what Tailwind let me not worry about.
