HBS vs. GSB

I think this "deciding again" thing sounds bullshit, so do whatever you want.

I'd go with HBS to diversify your network but you can't really go wrong here.

I tend to think GSB is the more elite option. Much more selective, higher GPA, higher GMAT, higher starting salary post-graduation, and most people who get into both go to the GSB. I think among the masses the Harvard name always resonates a bit more, but in truly elite circles (those "in the know") there is a bit of a premium on GSB just because it is so hard to get into. It's sort of like the difference between Yale and Harvard law schools in a lot of ways.

You already have 2 degrees from S. Go H.

Go to HBS for an MBA and Stanford for PhD. You will be a very smart 40 year old graduate.

You already have the Stanford network. What's the point of having a 3rd degree from the same school? Go to Harvard.

Go to HBS. You'll be able to return to the Bay Area.

Normally I'd always recommend GSB over HBS but this is one of those rare scenarios where it makes sense to take HBS over Stanford.

Note that at HBS this kind of humble brag from the OP needs to be modified to fit in the culture.

HBS 100%

I'm so angry about some comments.

1. HBS has higher yield rate than GSB (91% vs. 89%), meaning both schools admit very different students. The % of dual admit who chose HBS is around 60% according to different surveys.
2. A bigger class size is purely due to HBS's unparallel scale. If you have visited both schools, HBS has a separate campus that just looks like a resort while GSB only has a couple of buildings. Seven Noble Prize winners in HBS plus a lot more faculties need to be fed with more students. The case method also requires students with different background.
3. The median GMAT, the GPA, and the median pay is also the same among two schools - which is more difficult for HBS given its bigger size. But this is truly not important.
