One pizza in NYC to rule them all

I hope this is the right place to post. I'm going to be NYC for a day visiting Columbia and staying with someone in western Manhattan. They have offered to take me out to a pizza place of my choosing (I'm on the dole and am privileged to have their hospitality). I understand the big three to be Una Pizza Napoletana, DiFara's, and Totonno's.

When I was employed and stationary I was a regular at Apizza Scholl's in Portland, so I have been pretty spoiled. What would you suggest I select out of these three? Which is the most true to New York? Which is the most delicious? (I think the which is most true to Italy question is already answered by Napoletana).
