Author here, I haven't had time to play around with it, but this library[0] from Atlassian looks like a "best of the both worlds" styling approach: CSS-in-JS authorship without the runtime penalty.
If you like the idea of tailwind and don't want to look at utility classes and still want the power of styled-components or react-emotion I'd check out Chakra UI [0].
