Not in taste, not in texture/airiness, not on quality what exactly do you believe is similar? They are both pizza! Just to clarify, I walked into this argument fully aware it is subjective. Maybe I've just never had good NY pizza when I'm there. If you let me know your favorite NY pizza you swear by, I'll give it another shot when I'm there. In all honesty I've only had it as a tourist as I have family there. Locals usually have a more developed sense of where the best example of something is.
