Totally anecdotal, but the worst roads I've ever driven on were in Canton, OH. Seemingly every other block had massive potholes that could seriously damage your car.

The worst roads I've ever observed (but didn't drive on) were in New Orleans. In fact, the road quality was so bad there, it made using their bike share system extremely unpleasant. Sidewalks there were also pretty terrible. I'd hate to be a disabled person in NOLA!
