Which carrier would be better for iPhone 5?

I have AT&T now but I might switch to Verizon. Service wise I want to know which one would be better for the iPhone 5?

Verizon is the best where I live. But you will not be able to use your AT&T phone with the Verizon network. You will have to get a new phone through Verizon.

Verizon is great, but be prepared for them to milk you for every nickle and dime. Please consider that At&t is the only carrier that allows you to talk and surf the web at the same time. I left At&t for Sprint and wished that I would have stayed with At&t just for that feature. I'm trying to get a unlocked phone and do the no-contract thing, which to me is so much better since before now pre-paid phones use to suck.
