The biggest advantage of the #1 seed is that you already advance past the wild card round without having to win a playoff game. That is a huge advantage.
I understand downplaying the importance of winning the division and playing home playoff games due to our relative lack of success in recent years in those situations. However, I would attribute that more to random statistical noise more than any suggestion that we somehow have less of a chance at going to the Super Bowl as a #1 seed.
Beating Detroit, winning the division, and being the #1 seed should all absolutely be goals along the way to the Super Bowl. You can get there without accomplishing those goals, but it definitely makes it harder.
At the end of the day, the statistical and historical fact is that far more Super Bowl winners were #1 seeds in their conference than any other seed, for good reason. It is the path of least resistance.
