I sorta learn Angularjs, well went through a few tutorials on Angular for a company. Turned out that company is now doing emberjs and I have to learn emberjs.
I have to say EmberData is not production ready. It's modularity is more monolithic compare to Angularjs. There's a lot of moving parts that can break (in term of using emblem, brunch, handlebar, etc...). And the community is much smaller, less books, less people that talks about ember/tutorial etc...
Angularjs, it seems much better but the scoping can be a hassle.
I feel like angularjs is winning right now in term of hype, community, resources (books, blogs, etc..), and overall I feel like angular got it right and more ready (cause emberdata ain't ready).
On the plus side, ember got a cute mascot and angular got nothing...
Although this is just my initial reaction and it can change over time. Hopefully Ember will get better but if I have a side project I would chose angularjs over emberjs right now. Unless ember changed for the better.
edit:
direct injection is pretty awesome in angular btw.
