I've been using Polymer for several years on my side projects - Based on pure technical merit, I've always liked it the most of all other front end frameworks (though I have to say that in the early days performance and cross-browser compatibility were issues; but it's no longer the case though; now it's just great). Most companies these days are using React or Angular 2 (that's what I've been forced to use as part of my contract work). VueJS is getting traction but I don't feel that Polymer is getting the recognition it deserves just yet (it's very hard to find Polymer contract work). I really like that I don't need a separate compile step to build an app (almost no setup). The way the components compose together is also really nice. The CSS style encapsulation of Polymer 2.0 is another great feature - It might upset a few people due to lack of automatic backwards compatibility with external stylesheets but I do think it's the right long term decision. If someone is starting an app from scratch today, I think that Polymer 2 is the best choice.
