Well the whole point is unless you know they're an A you shouldn't really care about comparing them, so the investment terms and external factors are probably better indicators (like location) for making that decision.

I'm not dismissing the value of mentoring that easily. Just because I don't go to the Ivy League school doesn't mean it's irrelevant which university I pick. I've spend most of the past 2 months going around and talking to as many smart people I could and it had a tremendous value for me. I greatly improved my business plans, my pitching skills and pretty much everything about my project (everything but the product itself).
