Hi nicolasmoreno,
If you're interested in a School simply because of name recognition, then you're going about his process with a rather 'incomplete' way of thinking. You need to define YOUR goals and what you want an MBA to do for YOU. Once those variables (and a number of others) are clear, then your 'first-choice' School/Program should be far easier to name. It's possible that neither Harvard nor Stanford is actually the best School for your future/career path - and committing the time, energy and money to attend either School could be a relative 'waste' of resources if the degree didn't 'match up' with your plans.
Are you interested in a particular type of degree/Program?
