We're switching from asp.net to js (yay management ) and I was put in charge of looking for best js framework and vendor that can help us during the switch.
It's a business application and critical features are validation (business rules), orm (pgsql compatible) and support (community, etc.).
We had been approached by two different consultants, one offered solution based on angular.js and other one ember.js and I just want to make sure that I make the right decision.

Thanks !!!
