Well, I've been using React Native for mobile development for 3 months and everything is working well, the platform specific code can be easily written with a simple if statement or, of course, the same way as you do on Xamarin, it's up to you
Even being javascript in the end, you still can access all the native stuff with ReactBridge without any headache in the case you have some specific functionality that you might and haven't found in the lots of available packages out there :)
