Application advice

Hi guys
I was wondering if i could get your opinion on a couple of things.

I am applying to 4 schools

The schools are(in order of prefference based on my research of the programs)
University of Penn. (Wharton)
Amazing Finance program, new learning modules are better developed and organized than what most schools have.
But i dont like the fact that the class is so large. I feel smaller classes provide better chances to all since you have a better chance of developing close ties with faculty, other students and career alumni.

Stanford
Class size is ideal to give everyone a chance to stand out, amazing entreprenuership opportunities
Fundamentally balanced in terms of Case methodology and theory. The opportunities for private equity and venture capital (which is what i want to get into)

Chicago
Amazing flexibility and class choices. Finance dept is excellent, and Chicago in general is known as the most "think outside the box" school. Would be great in helping me look beyond the horizon in some ways.
Cons: everyone says it is too nerdy and people do not come out truly business savy

Harvard
I know most people would think i am crazy to put harvard as only my 4th choice in a list of 4 but here are my reasons.
Case methodology works for marketing, and entrepreneurship but for finance it only makes things unnecessarily burdensome. I am more of a quant guy, and like the old school- theory and then practice routine. Also from what i have seen of prospective students choosing harvard as a top choice, and those that have graduated, they seem to focus on marketing themselves so much that it gets overwhelming. To some it up, i come away from talking to a harvard alumni feeling like WOW he is smart as hell, but wait he didnt answer my question did he?
I want to apply there cause of their name and i feel it might be my best shot because they seem to be emphsizing on finding younger candidates even more this year.

It is very possible i am just simply wrong on alot of counts and if so please do tell me why, i would greatly appreciate it.

To sum things up, here are my credentials:
GMAT-720: Q49 V39 AWA6.0
B.S. Economics; Minor-Statistics and Finance (GPA 3.69)
Work Exp. currently 1.5 years @ a big economic company
Position: Research Assistant.
But i have done alot of work for independent development project
