Also curious if someone has anything to say about Vue/Nativescript. That would be my choice as well. I'm constantly wondering why React Native gets all the attention when Nativescript seems to have so much going for it.
Imo it's hard to justify betting a product on significantly smaller communities like nativescript/weex. Also when other companies have successfully used rn in prod like fb, insta, airbnb, the stress testing has already been done for you whereas I know of exactly 0 large scale deployments on those frameworks (even flutter had the Hamilton app)
