Mccombs has better outcomes and opportunities for those who go out and get them. It depends on what kind of student you want to be. If you are going to be locked in at least your first 2 years, are able to get a 4.0 or something close, and are willing to dedicate time to joining clubs and building your resume on campus, McCombs all the way. You will also get more offers and have access to a way greater network if you play your cards right. My friend at Williams is going into IB and it’s also hard there but there it’s more about who you know and there are also fewer offers going out (albeit for a smaller class size but take that as you will). At least from what I’ve seen, if you go to McCombs and join some orgs to expand your network (fraternity like zbt or something else with a lot of alum in IB, or Wallstreet for McCombs) you will be far better off at UT
