First of all, congrats on being admitted to all these amazing schools!
I mostly agree with MBASomeTime's assessment re: industries below, although I will add that I would take Tepper at your current scholarship amount if you are dead set on going into tech. Carnegie Mellon's CS program is very highly regarded and I think that would spills over into B-school recruiting.

Anyways, to provide more concrete decision-making, I would decide as below:
Finance/MBB consulting - Stern
PM/"Tech" - Tepper at 50%+, otherwise toss-up
Consulting - Emory
Also, maybe thinking from two other perspectives:
Location: Do you have a location that you want to end up in? If it's West Coast, then I think there isn't any preference, but if you looking to go to Austin, I would lean towards Vanderbilt/Emory based on geography. Similarly, if you were looking at NYC, NYU is hands-down the best choice. While neither location has the breadth and depth of SFO/bay area, the tech presence there is still quite large.
Class Size: How much does that matter? Emory/Vanderbilt skew towards smaller, Tepper is medium while NYU has a (relatively) large class (although nothing compared to places like HBS/Wharton/Kellogg).
