Congratulations on your admits and great offers!
Where do you want to be long term?
If you want to a 2-year program with an internship, then Fuqua. (MBB internships are super duper hard to score though, so even harder than a FT position). If you want to work in the US long term, then Fuqua as well.
If you want to get back to work faster, then INSEAD.
If you have more work experience and older, also INSEAD
Finally, if you want to work in Europe or Asia, then INSEAD.
MBB is always competitive in both INSEAD and in Fuqua. I feel INSEAD does a really good job since there is not a whole lot of feeders into MBB globally and it feels (based on the semi-transparent employment reports), INSEAD has an edge over many other schools when it comes to consulting/MBB placement. However, INSEAD is super secretive - they provide no data about their admits, numbers, etc.
The two programs are quite different and have different pace and .... I can't think of what is actually the same about them
