I strongly suggest you trying RN. Many of the issues related sloppy transitions is using modules that runs UI-driven changes on the JS-thread rather than utilising the power of doing it natively. For example, rather than using https://reactnavigation.org https://reactnavigation.org for navigation, consider using something like https://wix.github.io/react-native-navigation https://wix.github.io/react-native-navigation since all screen transitions are native. Combine this with the power of Firebase, you can use https://rnfirebase.io https://rnfirebase.io and you'll have an app up and running in no-time.
