We use Marionette in production at work. I enjoy it. I've supported existing Marionette applications and have also built a pretty complex calendar app using Marionette from scratch. Marionette seems to match up with my "intuition" as to how things should work. The ability to effortless swap modules and views in and out of regions is great. I'm not sure if that is hardwired into other Javascript MVC libraries and frameworks but if it isn't, I doubt I would like them. I've had some other experience, I built a beta site for a startup using regular Backbone. I've also built a pretty complex site using Batman.js but it never got to see the light of day. Other than that, I've just toyed with Angular and Ember.
