I was using Radium for a while, but switched to CSS-Modules and never looked back once. Its so much nicer, and you get to keep everything that CSS already has, including a sane readable dom and the ability to inspect elements (not possible with inline-styles when your output is all `style={...huge giant mess...}`). On top of that you still get to use your favorite CSS preprocessor if thats your thing. There's no comparison IMO. CSS Modules fix the scoping issues, and `composes: otherStyle` fixes the rest.
