NativeScript is pretty good. It can be used without a framework, or you can use it with Angular or Vue (and perhaps others). I used it with vanilla ES6 about a year ago for a side project. After finishing the project, I ported it to RN to compare the two. At the time, I felt that RN had the upper edge, because it could hot-reload updates more quickly. I suspect that the NativeScript team has made progress on that since then, though.
