Having used both at ISP's I can say though ATT is a better quality service, and more responsive to trouble, their sales cretins are absolute liars and shouldn't be trusted any further than you can throw them. if they represent something, GET IT IN WRITING,SO YOU CAN SUE THEM, as they are simply NOT to be trusted.
Never again will I use Sprint for an IP connection. They oversell many times their bandwidth and the service sucks if there is a problem.
