IPhone 5: What cell phone company should I buy it from?

Well, i never had a phone and wanted to buy iphone 5 but i don't know which cell phone company is the best. Which one has the best LTE and stuff which i don't really know. Rogers or Bell?

I recommend Verizon Wireless. They have the largest 4G LTE coverage in America. Although the price is very high. Second I recommend AT&T. They are the fastest the 4G but not biggest. Sprint is good but has slow internet.

Rogers.
