Radix UI and shadcn/ui both answer the same question: where do your components come from? Unstyled, accessible React primitives that handle focus, keyboard and ARIA while you supply every pixel of design. Not a dependency but a set of components you copy into your repo, built on Radix primitives and Tailwind. Both cover the ui kit layer competently, so the decision comes down to which set of tradeoffs you would rather live with for the next two years.

Neither is better in the abstract. Both cover the ui kit layer competently, so the decision comes down to which set of tradeoffs you would rather live with for the next two years. The wrong choice here is usually recoverable, so weight speed of decision over certainty.
You style everything yourself, which is real work before anything looks finished. Only primitives, so higher-level pieces like tables or charts are missing.
Copied code means bug fixes upstream do not reach you automatically. Every project ends up with a slightly different fork of the same components.
Usually, at a cost that grows with how much of your product leans on the ui kit layer. The sooner you wrap it in your own interface, the cheaper the exit stays.
