US vs UK

I have just finished with school in India. Out the the 13 universities that I have been admitted into in the U.S. and U.K., I am choosing between:

Indiana University Bloomington (Kelley School of Business)

&

University of Warwick (Warwick Business School) - International Management (4 year course with 3rd year study/work abroad; a chance at Wharton and Cornell for the study abroad year)

Could I please get a few suggestions on where to go for my undergraduate studies and a few points of distinction?
