Harvard vs. Stanford for MM PE?

I know this question is going to make me sound like an asshole but I am having an incredibly difficult time making a decision between the two. Without going into excruciating detail, I'm a PE associate in Chicago from a Big 10 undergrad who somehow was admitted to both HBS and GSB. It's clear the HBS and GSB offer a significant advantage for the East and West coast respectively, but what if I want to stay in the midwest? Does either offer a tangible advantage there? How do they compare lifestyle / experience wise? I've spent minimal time in either Cambridge or Palo Alto outside of admit student days so I have a hard time saying where i'd prefer to be for 2 years. Thanks!!
