Top 10? I think your top 10 is not a real top 10, and is thus crap. The top 10 business schools look like this:
1: Stanford
2: Harvard
3: Northwestern
4: Columbia
5: Dartmouth
6: Chicago
7: UPenn
8: Berkely
9: MIT
10: Cornell
See how that list doesn't even include Yale, Princeton, Brown, NYU, etc? When it comes to business schools, the elite schools truly are king. That name will get you into the Fortune 500, the Fortune 100, etc. It will open doors, get you interviews, internships, and so on. The alumni networks are phenomenal. The career resource centers truly help. The companies that come recruit at the job fairs are the real deal, and are not going to waste their time at state schools.
OP, if you have the grades and accolades to get into a truly top school, you should absolutely do it. The name matters even more than you probably think it does. The education may or not be superior, but the name and resources make it all worthwhile. This is almost certainly more true in the business world than for any other major.
