Which credit card (gas rewards card) should I get?

Question by that_photo_chick07: Which credit card (gas rewards card) should I get?
http://www.creditcards.com/gas-rewards.php

Is the site with all of the information. I've narrowed it down to Capital One No Hassel Points Rewards (the first and second to last one). Citi Dividend Platinum Select Master Card, The Chase Perfect Card *Gas Rewards Card*, the Citi Diamond Perferred Rewards Card. I'm so not a math person, but I know there is a way to figure this up.
