King's College London vs NYU for Economics (US Student)

I’ve been accepted to both for economics - CAS in NYU. I want to get a job in finance, possibly investment banking, and I’m mostly considering job placements. King’s has a higher world ranking on Top Universities, but does it have the reputation needed to get a good job in America?

NYU is far more expensive and will take four years (as compared to 3 for Kings), but money isn’t a huge factor in my decision.
