The Woolworth is IMNHO the best building in New York City. Built in a time before absurd zoning restrictions, where men of courage built wealth and manifested it in beautiful buildings.

It is definitely in the top 5. It might be overlooked by the art deco love but its extremely detailed and high quality design and craftsmanship is unique.
It is a classically styled skyscraper after all.
And probably sufficiently tall, no taller buildings don’t make sense in a hyper dense environment.
