Ask HN: Is React Native enough to justify using React over alternatives?

The discussion on Gitlab's choice of Vue.js got me wondering about everyone's thoughts on this. I hear a lot about front end frameworks but based on everything that I've read about React Native it seems that it gives me the impression that even if Vue or something else might be preferable - the potential cost/work/time savings of React Native would win the decision every time. Is there more to it?
