Why does Ember matter?
That said,

I don't want to self promote but I am sure you can find my other posts, I am creating a web app once every 2 or 3 weeks with ember and firebase - the beauty of conventions over configurations and of opinionated frameworks.
There 50 ways to setup a react or angular project. There is ONE way to do it in ember. You can move into a new code base and know exactly where everything is. (ps: you could change the conventions if you wanted, but why would you do that!!!)
