Okay so from my experience I'm going to say Vue. That's because I use it on many projects and implemented it in a few different ways depending on the underlying back-end stack. It is very versatile and flexible, and you have many choices available as a developer. There's also the support from the community, and I like the fact it wasn't created by an evil corporation like Google or Facebook.
That being said, React is obviously a good framework, but in my opinion it is not as flexible as Vue from the developers point of view as in how it is used/how you use it.
Angular, it looks cool, but I can't see why I'd choose it over Vue.
