The honest take
One World Trade Center is 541 metres to its architectural top. The observation deck is at 386 metres. The building's Vanity Ratio is 28.6% - 155 metres of the tower above the highest deck are structural but uninhabited. One World Observatory is an excellent viewpoint. It is not in the top 10 observation decks by honest elevation. Those are two compatible facts.
