"weeks" ??
Damn... I remember when I had to choose between angularJs and other JS frameworks a few months ago. Reading your comment makes me feel really good with my choice.
I've played around with Angular quite a bit lately as well and I definitely prefer Ember. You should really try both of them out and give them both a fair chance.
Also, you don't have to use data with Ember, it's just a benefit.
