When should I use RequestFactory vs GWT-RPC?

Question

I am trying to figure out if I should migrate my gwt-rpc calls to the new GWT2.1 RequestFactory cals.

Google documentation vaguely mentions that RequestFactory is a

Is it fair to say that when considering a limited MIS application, say with 10-20 CRUD'able business objects, and each with ~1-10 properties, that really it's down to personal preference which route to go with?

If so, then perhaps projecting how your application is going to scale could be the key in choosing your route GWT RPC or RequestFactory:

1. My application is expected to stay with that relatively limited number of entities but will massively increase in terms of their numbers. 10-20 objects * 100,000 records.

2. My application is going to increase significantly in the breadth of entities but the relative numbers involved of each will remain low. 5000 objects * 100 records.

3. My application is expected to stay with that relatively limited number of entities AND will stay in relatively low numbers of e.g. 10-20 objects * 100 records

In my case, I'm at the very starting point of trying to make this decision. Further complicated by having to change UI client side architecture as well as making the transport choice. My previous (significantly) large scale GWT UI used the Hmvc4Gwt library, which has been superseded by the GWT MVP facilities.
