I too struggle with the choice. Polymer/web components _might_ be an easier sell to my boss as it doesn't require as much framework specific knowledge and would make it easier to get new teammates up and running.

However, the polyfills + ammount of http requests in a very modular project don't inspire the confidence that Polymer is ready for prime time.

My thought is that when web components lands in browsers natively, and if some of the request problems are smoothed over, it would be easier to translate a react project than a project in another framework. You could replace things piecemeal. But by then, who knows how much more compelling react might be.
