Hmm .... looks like you are more interested in becoming an Art Director who is usually in charge of the "look" of the magazine, or a fashion editor who is really just a fashion stylist (or is sort of the head stylists) and picks the fashion to be featured in the editorials, than a journalist who only writes articles. I will say that fashion editors and creative or art directors have very, very different skills than jounalists and the path to get there is usaully very different.
I can't help you with which shool would be better because I have no experience with either of them, but we have the following threads that might have some good information in there, if you actually read them:
Careers / Jobs / Positions in Magazine Publishing
What Education is Needed to get into Magazines / Publishing?
How to Get Work in Fashion Magazine Publishing (see Post #1 for related threads)
And we have threads about Parsons and FIT .... but not about NYU, since it's not specifially a fashion school:
Parsons School of Fashion, New York
Fashion Institute of Technology (FIT), New York
Parsons vs. FIT (Fashion Institute of Technology) in New York?
