Leo says it largely depends on if 4G is in his area for his wireless carrier. It also depends on how he uses the smartphone. If he's a heavy user of data, then 4G/LTE is a good option. He also wants to be able to surf online while on a phone call, and Verizon's LTE network would allow that as opposed to their 3G network. If he's happy with his current phone, there isn't a compelling reason to upgrade to 4G. Battery life also isn't near as good on the 4G/LTE phones.
