Which phone would be better out of Blackjack 2,Palm Centro, or the Pantech Duo for AT&T?

I am teenage texter. All of those phone has qwerty keyboards so thats good but I am just not sure which one I should get. I am able to get either one I want. I like different stuff about each of them for instance, the palm centro I love how you can "chat" when you text and the touchscreen capibility. For the blackjack 2 i just like how it is a bar phone but i dont know much about what it does. And the Pantech I like how it can slide both ways but also i dont know much about what it can do. Please Help Me Out.
