My stance is of quality software. I really don't care what technology you use as long as that technology (and the mindset of the developers using it) allow for creating that quality software. RN, in my opinion, does not. Xamarin is a much better tool, from my limited experience with it. Xamarin Forms is just as terrible, though.

Any software that does not use the full benefit of each platform it is running on is mediocre at best for me, let alone something that is limited to a single thread, and reinvents the wheel for simple and/or solved stuff, such as navigation, animation and OS widgets.

I do think that of all the cross-platform approaches, going the native UI and C/C++ business logic approach is best.
