Which is a better company for and iphone 4s at&t or verizon?

I'm buying an iphone 4s from amazon soon and I want to know which is the better deal?

Both companies' monthly service rates are about the same so it really comes down to coverage area. Many people consider Verizon to have the best coverage overall but my recommendation would be to check out each company's website and look at their coverage in the areas you plan to use your phone the most.
