The React Native community is not as active as the React community, offering fewer tools, but it is sufficient for most tasks especially if you are a React developer since there is not much learning curve to get into potential markets.
NativeWind is pretty good but has no UI components and lacks compatibility with other libraries.
React Native Paper is one of the best options with the most users in the React Native community.
React Native Elements is also good but has fewer users and less consistent design compared to React Native Paper.
React Native UI Lib, created by Wix, has fewer users and npm downloads.
Gluestack-UI (formerly called NativeBase) is not stable at the moment.
React-Native-Reusables, based on ShadCN, is also not stable for now.
Currently, I use React Native Paper, React Native's provided components, and Expo components for most tasks since they are stable, have most of the components I need, and are supported by tutorials and community help.
