Academically, I really wanted to opportunity to take advantage of the internships I could do during the school year and I really like the idea of Stern's programs and the community building they do there. Granted, you can get an excellent education at Ross and their dining hall that caters specifically to kids at Ross is incredible... but I think I also like the idea of majoring and not just getting a BBA and doing concentrations. If you are really set on marketing/consulting, I think Ross is stronger than Stern in that area.
In choosing Stern, I knew what I'd be be giving up: the campus, the closeness to home, the tailgating/football games, and pretty much everything I've looked forward to since I was a little kid picking Michigan over State. But think of all you could potentially gain, you'll have the greatest city in the world as your campus.
Personally, though, I had to consider that I should get out of my little suburban bubble and be more independent. In addition, my sister lives in Queens, and I haven't seen her more than three times a year since I was 10, so I particularly want to rectify that.
This'll be a tough decision... I hope you've visited both schools and you pick the one that's right for you come Friday. Good luck! Not gonna lie though, I hope I cross paths with you in the fall.
