That would largely depend on expected outcome.

Do I want to be a Supreme Court Justice? Ivy League all the way.

Do I want to be a software developer? Coin flip.

Do I want to be a professional engineer (with a PE)? I go they give me the most financial assistance, as graduate school is likely to be more important and I need money for that too.

Do I have no idea? I go where I had the most enjoyable* campus tour/prospetive weekend.

* And that varies by student - party vs courses vs whatever else.
