I think that they are similar enough in respect to job prospects that you should choose the one where you feel like you feel most comfortable. I don't believe it's true that GW places better in the NE significantly; Vandy sends a lot of people to NYC. Also, a lot of GW people go to Atlanta. There is bound to be a lot of back-and-forth discussion in this thread over which is more national, but I don't think anyone knows the answer. If you really love DC, I think that and the overall atmosphere of the school would be on what I personally would base my decision.A big difference in my mind is that I think there will be FAR more gunner types at GW than at Vandy. I recently had lunch with two Vandy grads and a GW grad, and all three agreed that Vandy is probably more relaxed and GW is more cutthroat. I personally want a more laid-back place.
GW is much better for the NE than Vanderbilt.
