I find I am more productive with vue.js. It is much less intrusive on my coding style. I believe react.js is mainly popular because of FB's support. Much in the same way Angular became so widely used due to Google backing. I too have fallen for the myth that Open-Source projects backed by huge companies are always better. Do your homework. Don't believe the hype.
As someone approaching web front end development from a clean slate (es6 isn't the monster I though javascript to be, though there are some warts), can you tell me what vue does better than the alternatives (e.g., react)?
I'm building my first prototype of a web-based application right now, and sticking with raw ES6 to keep the cognitive load down (relative to javascript + a framework), but I'm likely to switch to one framework or another to get ride of some of the boilerplate I see happening.
You should try it out. There's no good way to answer the important questions with out putting in some effort. but... Vue.js is really fast. It does not require that you template your HTML in a special language like react. It works well with Jade and Stylus. It's really well documented. It's stable.
