Having read through the thread, I have to say that Mars has covered this off completely...1. This is a no-lose, win/win scenario. Whether you take the sultry PHD brunette Miss Brazil to the New Years Party, or the long-legged blonde professor Miss Sweden, either way, you're in a good place right now and your future looks pretty rosy too. Amazingly if you do take Miss Brazil, Miss Sweden will be content to wait, and vice versa (which is definitely where the analogy falls down...!)2.. If this was a run-of the-mill PE firm then I'd say stay with MBB and do the MBA for free. The value of an MBA is in three areas - 10-20% academic teaching, 30- 40 learning from other (hopefully brilliant) students and 30- 40% alumni/brand/club membership. Yes, the academic aspect is important, but you'll learn much much more from working with brilliant, international open-minded people from other industries and you're buying into a club. That's why an MBA from North Surrey is a waste of time (no brilliant colleagues and a club no ones heard of) while INSEAD, HBS, LBS etc are worth every penny as long as you come in the top 20% of your year.3. However, the PE houses you mention are not run of the mill. They are in my mind equal to the brand value of the MBB (Bain Capital came out of Bain Consulting for example) with the added value that they actually buy businesses and increase their value using MBB techniques. They don't just sit on the sidelines like the MBB taking day rates.But frankly - you can't lose - there is no mutual exclusion in any of these options.
