Ember definitely smashes Angular in terms of 'big apps', it seems it's somewhat behind Backbone.

Ember:

* Vine

* Twitch

* Square

* Heroku (dashboard)

* NBC News

* Discourse

* Huboard

* Travis CI

Backbone:

* Rdio

* Hulu

* Disqus

* Khan Academy (also uses loads of React)

* Stripe

* AirBnB

* Pandora

* Trello

etc etc..

Backbone has been around a lot longer, but Ember's apps seems to be built more recently.
