They are super hype driven, now let me hype you for my personal fav.
Vue is the most similar to vanilla JS that I've used so far. It stays out of your way and works like you expect it to. I like that it only handles the render layer. It says to you "Give me a template and give me data. The data is up to you, I'll handle keeping the template up to date."
I'd love to use webcomponents but they're not going to totally replace these toolkits and right now the polyfill you need is atrociously slow.
