I am not able to attend enough games to really weigh in on game day experiences, but if your competition is the "living room", you should take a look at (1) the comfort/quality of the seats, (2) the food, beverages, and other comfort amenities, and (3) the wifi, information, and second screen experience. This is in addition to logistics of getting to/from the game and tailgating, etc.
I don't know about the wifi, but GT has always scored pretty low on the other two.
That barely accredited university in Chapel Hill is putting in all new seats and shrinking their capacity. Not a bad idea.
