Personally I think css utils are better suited for layout related stuff, acting more like layout primitives (hbox, vbox) etc since those tend to be pretty ad-hoc.

As far as concrete UI components go, I'm not sure this technique is any better, especially since you often need pretty ad-hoc styling with pseudos etc.

I think if CSS had built-in mixin support you could have the best of both worlds pretty easily, still crossing my fingers we get that some day, would be nice to drop all these build systems.
