Who will win the superbowl?

Both the Seahawks and the Patriots started this year as an average team. After playing the Chiefs, both team improved both offensively and defensively. While the patriots Won the Championship game convincingly (ALTERED BALLS DO NOT MAKE A TEAM LOSE BY 38 POINTS), the seahawks struggled and barely won. Which team has the edge in this superbowl? it will obviously be the better team, but we have to wait to see which teams show up?
