Tough break, regarding the two scholarships
Anyways, here's my two cents.
I think Darden provides a better MBA Experience, at least for what I'm looking to get out of my MBA.
The classroom experience is vastly superior to that of the two other schools I visited, which counts for a lot in my book.
There are also a lot of little things like the Darden Cup, the 100 case party and other Darden traditions, the smaller class size and small town in a warm climate, that add up to a better overall experience.
From a career prep standpoint, I want to go into General Management (not completely sure what area), so recruiting is very similar, but I think Darden's curriculum would prepare me a little better.
Darden's alumni network is probably stronger, but Duke's seems to be great too, and is slightly larger for recent grads due to the larger class size, and is possibly farther reaching, again due to class size.
The area where Duke makes a strong argument (in my mind, at least) is the brand perception. I'm from Michigan, where nobody has an MBA. When I tell people I'm favoring University of Virginia over Duke and Cornell, they just don't get it. I'm not sure whether the people I will encounter in my career (coworkers, partnerships, customers, suppliers, etc) will have any understanding of the comparative strengths of MBA programs. This would make a nice case for Duke. That being said, I really hope I never even have to mention the fact that I have an MBA more than 2 years after I graduate, let alone where I got it from. I hope that my work experience would be the more important factor at that point, but I can't control other people's perceptions and priorities.
