If I were doing licensing from scratch, I'd go Datacenter, even accounting for the CPU licensing, it's not all that much more. The ability to add and move servers, "thinly" provision servers, etc makes a a much more robust environment.
When I say thinly provision servers, I mean, making a server responsible for only one task, such as AV management, BES, whatever, without putting additional duties on it as is common in a physical server environment. David: of the physical servers, if you had your druthers and could isolate the tasks out to an individual server, how many servers would you really have? Or are all those servers only doing one task, already?
