The Verizon version is GSM unlocked and will work on AT&T, T-Mobile, and all other GSM carriers worldwide. Therefore, as long as you don't need subsidized pricing, it's a no brainer to get the Verizon version if only for the resale value alone. This being said, I don't believe you can buy a full price Verizon version at Apple.com preorder. I believe you can get one at the store without them checking to make sure you're actually a Verizon customer, but I'm not sure there. Can anyone confirm?
