Both programs are tied at 19 in the USNWR 2022 rankings. I think Carlson is highly regarded and has great opportunities in the Twin Cities, home to many Fortune 500 companies. I think UW-Madison itself has a a little more “prestige” but not necessarily its business school over any other flagship U business program. You choice should also consider what you want to specialize in. Each school has strengths and different depth of curriculum and course offerings.
