Ember is an incredible framework that's been carefully thought out by a team of super sharp people with loads of experience, and I'm constantly amazed by how quickly I can get real projects built using it. I've used it for many projects since ember-cli came out a few years ago. I feel about Ember for client-side projects how I felt about Rails for server-side projects—it made it fun for me again.
But Ember gets a bad wrap from the internet because (admittedly) their marketing materials with the gooofy chipmunks make it look like a toy while React's make it look like you're learning quantum physics. And then there's the timeless "convention over configuration" divide where Ember people are generally on the left side, and React people just love the thought of fiddling around and hand rolling their own custom ungoogleable bespoke artisan framework before actually getting to the meat of the work.
I highly recommend using Ember for any size project if you like getting shit done.
