The Fordham employment report is rather vague. That is concerning. I would imagine the strength of the network is NYC-based, but perhaps not all that strong, especially given the part time programs, etc. Have you been able to connect with anybody in your desired field from there?
Vandy is better than its ranking imo, perhaps seen as "on the rise." Like others before it, I strongly believe the parent institution name will continue to carry it forward, and the quality of the applicants seems to have already matched schools in the 17-24 range.
All that said--your specific situation is not generic. NYU will undoubtedly provide the best opportunity for your career goal. Do you mind sharing your stats/background? I would also be curious to hear what other schools you applied to and the results (there are plenty between Vandy and NYU that could be good fits). Would you try again or are you set on going this year?
TLDR: I voted Vandy because it is without a doubt the superior program all things equal, and I would imagine the name would carry weight even if the network is less than extensive in your desired field.
