I suppose there's not a lot of difference between the two at the fanbase/team level. However, I'll look at it from a conference perspective: Ole Miss was more embarrassing.
I mean, we're talking about the big, bad, SEC here. They aren't supposed to lose to teams like Jacksonville State.
On the other hand, everyone already knows that the Big 12 sucks after the top 3. And even they didn't look to hot (Texas didn't do that well, and Oklahoma was very close to getting beat). And Mizzou, a team picked as the #2 team in the Big 12 North, should have lost to ILLINOIS, the team picked by many to finish DEAD LAST in the Big Ten. Yep, the Big 12 is REEEEAAAALLLLL strong this year.
