Which GWT EventBus should I use?

Question

In the gwt-user.jar there are 2 EventBus interfaces and SimpleEventBus implmentations.

com.google.gwt.event.shared.EventBus and com.google.web.bindery

Answer 1

To make the choice even more complex. I am using guava in my GWT application and the google guys have added yet another EventBus in there (even less feature complete).

Maybe those guys need to sit together and define ONE implementation to rule them all ?

Obviously I would like to avoid all dependencies on GWT for code that is not strictly used in GWT code, so the Guava one looked interesting to me.
