Both colleges can get you where you want to go if you do exceptionally well. And in general people do best in the environment they are comfortable with. Keep in mind that your undergrad college is but one small piece of the equation for grad school admission. For most top tier MBA programs you need 1) very strong GPA 2) very high GMAT https://magoosh.com/gmat/2015/gmat-scores-for-top-business-schools/ 3) 2-5 years of meaningful work experience 4) strong recommendations, essays etc.
My personal preference would probably be UR because I happen to like a traditional campus, but I would recommend that you go to the school you feel is the best fit.
