I like Cornell better, but Princeton has better name recognition. Can anyone speak towards the reputation of the Dyson undergrad business school at Cornell (AEM)? I have been admitted to both, and money and distance are not factors that make one more appealing than the other. I am planning to get an MBA either way.
I am not a fan of undergraduate business programs, even very selective ones like Cornell AEM or Penn Wharton. Go to Princeton and study whatever you find most interesting. Be sure to include some economics courses and math courses. After college work in business for 3 to 5 years, then apply to MBA programs. Business school is most effective for students who have some real experience in business. The majority of students at the top MBA programs have liberal arts and sciences backgrounds, not undergraduate business degrees.
Cornell is a terrific university, especially at the graduate level. Ithaca is gorges!
At the undergraduate level, it is hard to beat Princeton, with its smaller classes and the enormous resources it devotes to its students.
Princeton does have some large classes, such as introductory and intermediate economics courses.

Princeton does have a high math version of intermediate economics courses (requires multivariable calculus). This may be desirable if you want to go on to PhD study in economics, go into quantitative finance, or just happen to like math with your economics.
