Hm, DBmon benchmarks show that Polymer 1.x with polyfills is a lot faster than Angular 1.x which has thousands of production sites and was acceptable not that long ago. So I'm not sure that non-polyfill execution will really fix the performance for you. Maybe chrome is better at rendering your application structure?
