at&t, because they have a better service, you get reception in places you wouldn't with verizon.
at&t's phones aren't as good but they have both the iphone and blackberries.
at&t is much better than t-mobile because it is a more wide spread company.
after 9:00 you get free minutes with at&t, but i'm not really sure about verizon.
i hope this really helped, good luck!!
