A fair evaluation
Build one representative screen in each option. Check the required API, framework integration, keyboard behavior, loading states, package imports, and commercial terms. Existing team experience and migration effort often matter more than a generic feature score.
Do not assume that similarly named components have equivalent behavior. Compare the specific operations your users need, and use each project’s current documentation as the authority.
