Looked into tailwind 2-3 times and simply couldn't see the appeal. Working on analytical-dashboards in react, I mostly end up writing css straight in js using material-ui's makestyles. There's only so many components to style before I start reusing them and the css needed to make something 'not-look-too-crappy' is actually quite low.
Now after learning all the css basics, I'd have to learn yet another 'system' again? I think I'll pass.
On the other hand if I'd be constantly restyling webpages with hundreds of different components etc., I might consider it again...
