Only for counting supertalls and buildings that have antennas to make it a supertall:
In my opinion, if spires and antennas weren’t counted at all in NYC, then by roof height the future Grand Hyatt Tower would be the tallest building in the Western Hemisphere, followed by buildings Central Park Tower, 111 West 57th Street, 432 Park Avenue, 270 Park Avenue, One WTC, proposed 350 Park Avenue, One Vanderbilt, future 2 WTC, 30 Hudson Yards, proposed Penn 15, ESB, proposed 41-47 West 57th Street, 3 WTC, 9 Dekalb Avenue, 53 West 53rd Street, the Spiral (66 Hudson boulevard), 50 Hudson Yards, 35 Hudson Yards, One 57, One Manhattan West, Bank of America Tower, Chrysler Building, and technically the Conde Mast Building (4 Times Square).
If the spires/antennas were counted, then the buildings (including ones in roof height) will follow as; One Manhattan West, One57, 35 Hudson Yards, 50 Hudson Yards, the Spiral, Chrysler Building, 53 West 53rd Street, 9 Dekalb, 3 WTC, proposed 41-47 West 57th Street, 4 Times Square, Bank of America Tower, proposed Penn 15, 30 Hudson Yards, future 2 WTC, 270 Park Avenue, 432 Park Avenue, One Vanderbilt, 111 West 57th Street, proposed 350 Park Avenue, ESB, Central Park Tower, Grand Hyatt Tower, and One WTC.
