One question that popped up in my while reading the article was would you consider doing the android app in react native if you had to start now ? Or do you still feel it lacks the coherency it has with iOS.
While the performance footprint is mostly the same - the ecosystem and feature set around it has improved a ton to the point where I believe you could get it 90% there very quickly.
One of my friends has a small startup and they went full React Native as a team of two and they describe the Android side as "free" as in they really just focus on iOS and it 90% of the time it also works fine on Android (they care less about older devices at the moment so they don't spend time optimizing for those).
Android inherently will always have challenges due to the vast number of devices and hardware/performance problems but going native isn't a silver bullet either and doesn't shield you from the challenges entirely - it's just a familiar form of pain ;P
