The consensus at the Beretta forum is that there are no appreciable differences between the two makes. The question then becomes a subjective one- which country do you like seeing stamped on the slide? For example, guys who want one like the one they had in the military might prefer a BUSA-manufactured pistol whereas a collector interested in an example of Beretta's Italian heritage may prefer the Italy-stamped model. Either are fine, it's just a matter of personal taste and choice.
