I don't think I've offered any insight at all. I'm just asking questions to help you answer your question. Anyone could look at the rankings and work out what is the highest-ranked school that fits your budget, but the choice should really start with the goal in mind: what work do you enjoy, and would you want to devote your life to? If you just want to learn and to meet people, there are some much cheaper ways to do that. The LSE's diploma for graduates in management has much of the content of an MBA, for example.
