HBS vs. GSB

I got accepted into both HBS and GSB for the Class of 2020. I see several pro's and con's with each school for my particular situation, and I'm having a hard time deciding between the two. I'm interested in tech and want to live around the San Francisco Bay Area longterm, which I think would - under regular circumstances - lean in GSB's favor. However, I already have both a bachelor's degree and a master's degree from Stanford, so I think it would be valuable to get a different perspective for the MBA by attending Harvard instead of getting a third degree from Stanford, even if its focus area and alumni network are not as closely aligned with my interests in tech and the San Francisco Bay Area.

This is my second time deciding between Harvard and Stanford. When I was admitted to both for undergrad, I ultimately went with Stanford primarily because I felt I would be "happier" there. However, I'm not sure "happiness" should be what I'm optimizing for in my MBA, particularly because it's just 2 years and I feel like I have a much better sense of self now than I did at the start of my undergrad and I can "tough it out" if it means getting additional value in other areas.

What do people think?
