Not even close. Poor Verizon fanboy. Verizon does have more customers, after outright buying Alltell which was a carrier people fled to from Verizon. Also, that aside, Verizon does not handle the amounts of mobile data AT&T does. Never. Recall, AT&T mobility might be new, but AT&T Inc (or its Mother AT&T Co), has been around since early 1890s. They have handled more data than what you can imagine (even data through TAC-1).
In any case, iPhone users do more data transfers than Droid or Pre users do. Just go online and check the comparison charts.
