Currently, all our javascript apps use Backbone and a few use Marionette. I'm a fan of Marionette but certainly no evangelist for it. For me, it really soothes the main pain points I had with Backbone. All that being said, we are about to be forced to use Angular on a big new directive and will even have to re-write some of our old apps with Angular. I am very worried about this.

I went through exactly the same thing during last year. And if you liked backbone/marionette combination, you very likely hate angular :) BTW, make sure decision maker knows that Angular 2.0 should be released soon and there is no upgrade path between 1.x and 2.x :)
