The tooling for Flutter is better, but Expo brings React Native much closer.

I fend that React Native app "feel" more native because they're actually using native components, but controlled via a JS runtime. Flutter on the other hand mostly renders to a canvas and re-implements native controls (although it can also wrap native components like RN does).

This leads to there being less of an "uncanny valley" in React Native apps compared to flutter. It also means that all the little details from the system (the text selecting and editing interactions in text inputs being a major one) are idential to native apps when using React Native, because it IS the native component.

The downside to this is that you need to consider platform differences more with React Native, which is one of the things which leads to developers without mobile experience having issues with it.

As the article says, you get the most out of React Native if you're a mobile developer, or at least have someone on the team who is. You can't abstract away all the details of a mobile platform without some tradeoffs.
