In reality these few ms more do not hurt these companies. it is sad but true.
I think react native is always a better choice than tools like cordova while the best choice is native development. every time i use a cordova app it is painful and you just know something is off. react-native apps are a lot nearer to native experience. you can differ them if your really trying to though. but if your just want a good native ios and android app react-native is a good choice. and you can slowly learn native development from there and shift to native if you like.
