Serious question: if someone were to make you the editor of US News and World Report for the day that it issues undergraduate college rankings, how would you rank (in order) the 18 Big Ten schools (general undergraduate education, so if you think Purdue is better for engineering, but Michigan is better for everything else, Michigan comes out on top in that scenario)? Or, if you prefer, you can keep this to the B1G 11 (i.e., before Nebraska, Maryland, and Rutgers, and the west coast schools showed up).
Also, if you think tiers make sense, feel free to use them.
