MIT vs Stanford vs Berkley

Hi,

I'm a Ph.D. student in the UK and have been awarded a fellowship to
study entrepreneurship Stateside for 6 months.

I have a comp sci background and I'm keen to sit in on business,
computing and math classes. When I complete my Ph.D. I plan to start a
company, work for McKinsey or do an MBA. I have never been to
California nor have I seen Boston.

Where should I go and why? All feedback is greatly appreciated.

Thanks in advance,
Luke
