I've played with both, and my vote definitely goes to Tailwind. Tachyons popularised the concept of functional CSS, but it's very hard to customize (a lot of copy/paste, custom cli tool to recompile), whereas Tailwind has a per-project configuration file for colors, breakpoints, etc. and you can build components out of their CSS primitives (if you use PostCSS).
