Section 308 offered more of a corner end zone line of sight but to my surprise, the view of the field was pretty darn good. You'll be able to see all of the yard markers just fine and can still read the numbers on the back of each player's jersey. I could at least.
I had plenty of leg and elbow room at my seat in row 5 although I had to practically stand up to let someone by me to get out of the row. That was annoying. But other than that, I think I would recommend section 308 to any NFL fan, Chiefs fan or not. Be sure you purchase your Chiefs tickets online, that way you can choose where you want to sit because there is some room for error if you're purchasing your seats from a scalper on the street.
