Just curious, have you asked for more money? This is a close call--no doubt I'm biased but made a similar (Duke with $) decision. I think the arguments for Fuqua are:
1) Experience: Did you want a classic collegiate environment and a tight-knit community? If so, that intangible experience found at Tuck/Duke/Darden can't really be replicated
2) Money: 90k+ (especially factoring in interest) is significant and can adjust mid term goals like buying a home or starting a family or just general lifestyle
3) Desired Industry: If you had thoughts about finance (particularly investment management) I would say Booth no matter the cost, but given your goals of Consulting and/or Tech...Duke is quite strong in these areas and given that you are likely to stand out, that's a compelling story
Congrats on your awesome options and good luck!
