My current favourite, after trying Angular2, React and Vue is Cycle.js (I might be biased, I'm a core contributor), because the Stream based approach makes combining HTTP, websockets and other effects easy. What I also like is the flexibility of the Framework. The app/driver seperation makes it very adaptable. It uses Snabbdom like Vue and is quite fast. In fact, it was the framework with the highest (percieved) performance in the pythagora's tree example. Plus it is amazing for testing as seen in Nick's and my Talk.
