I don't have any practical experience with angular (but I'd like to, and definitely think its testability is a step in the right direction).

That said, I've found react to be very declarative, especially over the raw jQuery and Backbone I'd used before. Most of the components I write have no state, and render() declares how to render them from any state, without having to worry about how to change things on state changes.
