Web is the much more performance sensitive side, where it improves most. If you do pseudo styles or responsive styles with RNW your web app will absolutely tank in all metrics, runtime/lighthouse/load/layout. Tamagui fixes all four. That normally prevents code share for anything more than small apps or totally performance insensitive use cases, otherwise Tamagui makes a big difference.
