I got into Umich pretty early so I withdrew from all of the schools that offered me interviews after that. I wanted to go to Umich for 4 years but they didn't give me the scholarship package that I thought they would. Ultimately it was down to Duke, Umich and Yale. Yale had the best match list and was the best price.
General Advice: Apply early and make sure you spend time on your personal statement. I don't know if they read the secondaries as much bc for one school which I was offered an interview, I sent an essay with another school's name. Oh well...
