i vote for GSB....
GSB has that special rep within the financial industry ( i know - no IB for rhyme, but other paths such as IM, PE, etc...) and still has solid placement in other industries such as consulting, corporate, etc.....
since you're not exactly sure which path you want to take post-mba, i believe that GSB will give you a slight edge as far as options, esp considering that their curiculum is more flexible.
unless you're leaning heavily towards the marketing industry, my vote stands firm with gsb- but man, it's stillll such a tough choice!
what does your heart say?

i say you go with what your heart is telling you. oh yeah, should prob consider your woman's opinion too!
