I've also shipped an Ember app and a Knockout App. To me, there's no comparison: Ember development was easier and produced a faster app and a better organized code base.

Once my app grew complex, Knockout grew increasingly hard to reason about how it's view updating was working. It also grew slow.

Also, Knockout lacks any legitimate data laye (knockout-mapping isn't a data layer). Ember has ember-data.
