You can’t go wrong with either school. While I don’t put a ton of stock in ratings, you are comparing schools ranked #6 (McCombs) and #9 (Kelley) in the USNWR undergraduate business school ranking which I take to mean that they are basically regarded as equals. I imagine that students/alumni of each program could rightfully tout their school’s strengths.
If you don’t get a direct admit to McCombs then I’d go to Kelley. If you get the direct admit to McCombs then I’d say to visit if possible and then go with your personal preference.
