The only team in the AFC which has separated itself is the Chiefs. I feel like on any given sunday any of the other 6 teams could beat each other, which makes it almost impossible to predict anyone not playing the chiefs. The NFC on the other hand has 3 teams (Packers, Saints, Bucs) that could make a legit push for the Super Bowl, and a 4th (Seahawks) that is a good dark horse.
Overall Chiefs are big favorites.
