Ember is moving to a similar view model as React (though still having templates separated from logic) but isolated components with immutable state being passed down. React has a really vibrant ecosystems with lots of batteries to choose from, whereas Ember comes with batteries included. For example routing, test runners, controller/view logic concerns. Ember also has an optional data package called ember-data, with the goal of being the defacto way of dealing with server side state. It's fairly opinionated, but swappable with other alternatives.
