Variety
Different parts of campus look/feel totally different and unique
Columbia has a pretty cohesive design.. Penn wins this one.
-Close Community
Easy to make friends and hang out, find where you fit in
Neither really have this. But Penn gains slight edge.
-Good Weather
I'll let this one pass since both of the schools are very good. If the school is good enough, I'll brave the cold.
Meh, the same. But more fun in NY. So Columbia wins here
-Large/Medium Size
Big enough to feel like I'll never see everyone/everything
Penn is significantly larger. Is it large enough for you to not like it?
-Quiet, Peaceful Location
Suburban area next to a big city is best. I realize both of these schools are in major cities though.
Penn is a little out, in University City. Penn wins this one. But really, not be much lol.
-Good transportation
Must be easy to reach major airport because of how far away the schools are.
Both are really accessible. From Penn, it's a 5 minute walk to the station and a 20 minute train ride for 8 bucks. For Columbia, its a bus/subway/taxi ride to the airport. Cost varies.. but i think Penn wins this one.
-Easy to reach Professors
Should be self-explanatory. Good S:F ratio and office hours.
Meh, both elite privates. No winner.
-Good colors
School colors must be appealing to the eye, otherwise I will not apply. Just kidding, of course.
Okay, sorry to the Columbia fans, but light blue just doesn't suit me hahaha (Duke blue wins

jk). Penn wins.
sooooooooooooooooo I say Penn.

I hope this helps a little haha.
