Congrats Randomguy! You will have a huge debt either way
It really depends on your perspective. If you look at some of the feedback and debriefs from students, while there is on-campus recruiting and many students (50%?) get at least a starting job they can negotiate with that way, the best positions and best opportunities come from networking. If you are staying within New York or East Coast, Columbia would provide good networking opportunities. Harvard has a much greater reach - you can find someone even in Kenya who is probably son of the president or something who attended Harvard. People in the know, know that Columbia is Top 10 MBA but everyone including your aunt and your little cousin know that Harvard is #1
On the financial side, let's say CBS offered you 100K for 2 years and HBS did zilch. That's a bit difference at first. But consider all costs in your decision (I won't get into speculating about income or anything like that) but consider the cost of living ($40-50k/yr - definitely budget more than what the website says) being probably somewhat equal, though slightly less in Cambridge and the opportunity cost ($50-75K yr). You have CBS Costing you $250K vs. HBS $350K.
In part many here on GMAT Club would probably pick HBS just to get the ultimate experience and to be able to never doubt that an employer passed the school by because they had a better option.
Columbia has a few things going for it though - it is getting a new campus sometime soon (2018 or 2019) so the issue with the facilities should improve. It does have a better than expected community for a city school so all those are positive. NYC is a big financial center but I feel Columbia is somewhat lost in the noise - there is Tuck, Booth, Kellogg, Wharton, Stanford, Yale, Haas that all seem to have more going for them....
The reason I could not go to CBS is not being able to mentally stop questioning and doubting my decision. You may be a stronger person than I am and you can put the decision behind you and never go back to it. I over-analyze things all the time. Hoping the admit weekend be more helpful to help you lean one way or another.
Congratulations!
