Preferred way for Angular models and validation

I want to have models in Angular, I have found some ways to do it with $http, $resource, Restangular, Backbone(I don't actually like mixing frameworks). What is most preferred way? I have used EmberJS before and like the way how models are done there EmberJS models. Also, I have heard of Breeze library, any preferences using it?

Also I would like to have validation rules for models, I have found one library valdr that I actually like, but it seems to be missing some rules for arrays.

So, what are your suggestions on models and validation?

Thank You.
