Parse has a nice and simple inteface, also sdk is verry nice and easy to use.

Local database, be able to pin the objects. And the built in model mapping. Easy and painless. So far I didn't have any problem. I like the dashboard, but it could be improved a lot. In fact, I've been using parse more than 2 years and the dashboard didn't have any feature update. I like that the sdk is opensource, having control of my dependencies. And be able to use it in different platforms, watchkit, tvos, mac...

Funcionalidad, facilidad de uso, el nuevo panel de control aún en beta, pero muy potente.
