It looks, corporate world and serious projects already bet on more opinionated, more standardized option, so they bet on Ember.js. Luckily Ember.js is improving nicely, super fast, easy to use, easy to learn and a super smart community around it. CLI, data management, addon ecosystem are just a few feature, what makes it unique. Vue.js, React, Angular should learn from Ember, however they are 1-2 years behind Ember, so it takes a while to catch up.
