It doesn’t require you to take ownership of all of the underlying primitives like Shadcn/UI does, and the theming is much more advanced and transparent to me than Shadcn/UI. It also has more layout-related components ready to go than Shadcn/UI and with less mental overhead.
The closest DX I can think of is ChakraUI (for React), and in comparison to that, the SSR & Tailwind integration story can’t be beat (plus, it’s on Vue, which I prefer more).
