Comcast is so much better in many ways. They both try to say they'll save you money, but I've done both and in the end I ended up in collection with AT&T because they charged me for things I didn't receive and refused to take it off my bills. Their customer service was TERRIBLE. I finally got everything straightened out, but I would never recommend AT&T. Horrible customer service and bad service overall. Comcast, at least for us, is so much better.
