TNF gotham down jacket or TNF aconcagua jacket?

I'm going on a weekend trip to NYC and I am in need of a jacket that would keep me warm and toasty in NYC january weather. I really like the fact that gotham down has the hood, however, I also heard the jacket is 2 inches shorter on the back compared to the aconcgua. Ladies, what would be a better choice and why? I would appreciate your response!
