I use Tailwind, I like the fact that it's highly customizable.

Grommet - easy to get started and update your theme

I've never used Tailwind, but I love Ant Design. I like the standardized design language, but it's different from Material Design.

I've been a fan of Material-UI since they added SSR support prior to their 1.0 release. As I'm getting more into typescript, their TS support is amazing. Really easy to extend, theme, etc.

We actually used Uikit. It gave us everything we needed.

Today I'll have what fits. For smaller projects often just Bootstrap.

Tailwind CSS if my favourite for UI. Its balance between predefined and customization. I don't have to work with what framework designer thinks while I don't have to write cumbersome CSS rules. All it supports multiple frameworks with postcss and purge css which are just plug and play.

The new Hashnode design uses TailwindCSS. We had a great experience working with it so far. A detailed report on the design process and tools used is coming soon. :)
