Congrats on having two wonderful choices. Ross is a great school, but I absolutely don’t think it is worth twice the price of McCombs. Plus if you think you may want to stay in TX after college then there would be advantages to McCombs in terms of having a strong alumni network in the state.
I know people who went to UM and UT and they all loved their respective schools.
Not that any rating should be a deciding factor, but just to show how close the two schools are the USNWR undergraduate busienss school ranking has Ross #4 and McCombs #6 – that is certainly not a material difference.
