I’m trying out Ark UI on a side project. They do have some genuinely useful components, like tags input: https://ark-ui.com/docs/components/tags-input
They have a tabs/“segment group” component with a nice animated active element indicator which would probably be tricky to implement: https://ark-ui.com/docs/components/segment-group
And then they also have stuff like overcomplicated “click to copy” button and a <details> reimplementation: https://ark-ui.com/docs/components/clipboard, https://ark-ui.com/docs/components/collapsible
All with a verbose markup that renders as a div soup.
