I agree that styled-components takes care of a bunch of issues that make some of us reach for Tailwind.

However, aside from requiring a very specific tech stack, it doesn't solve the problem of every component potentially having slightly differing styles. There's ways to handle this, but one thing I like about Tailwind is that the defaults are stronger across components, while still leaving space to deal with all the one-offs.

I believe in some environments (when you have designs already) building off normalize+react-aria(for logic) and thought-out architecture could be as productive as tailwind, especially if you already have some helper functions on-hand. For me, storing mixins for common behaviours inside theme allows to construct lightweight variations where I need them, and you can dynamically modify it in react.
