I'd take Harvard over Stanford just for the name and opportunities that Harvard affords. Plus, I love the East Coast and Boston is such a great city for cultural experiences and historical monuments. Stanford over Yale because I grew up in the Bay Area and love it there. I'm just not attracted to Connecticut.
It's honestly a toss-up for me between either school. From what I know, I like both equally. I like the area that both are in and I especially love NYC in general. I'm not familiar with the city of Chicago (nor the school), but having spent several years on the quarter system, I'm not a fan. Plus, not sure if the conservative reputation is true, but that would drive me a bit insane.
I really like Penn's reputation. A friend goes there and she has painted a great picture
Michigan because they have a dual degree program I'm interested in. Berkeley over UVA just because I'm not a fan of living in the South (although, to be fair, I'm not a fan of living in Berkeley either).
These are almost virtually indistinguishable to me, so I ranked them in the order of ones I like best
