I don't think your posting gets the recognition it deserves.
You guys have me split now. Half of you hate AT&T, half hate Cox. No one loves either. I gotta make a decision in the morning. It's like Sophie's Choice.
Questions then:
Are you mainly looking for speed? Cox destroys AT&T there. If you don't need a lot of speed, then either would suffice I'm guessing. But AT&T can't put up the speed numbers that Cox does.
