No quibble with ranking Una Pizza Napoletana #1 though personally I’m not that into Neapolitan style.
I’m dubious about Tony’s being ranked #3. Their ambition is impressive but the consistency was not there for me, hardly surprising with something like 20 different styles of pizza with close to that many different doughs in eight different ovens.
The only other one I’ve been to is #50, Rose Pizzeria in Berkeley, which is a great place and I think would be somewhere in my top 5 in the area.
List opinion is largely based on people from Europe and Italy. Not necessarily for people in US.
They think more about leavening level on dough or characteristic of pizza than crisp factor. They also prefer true Neapolitan pizzas than neo or longer baked wood fired pizza. Because lot of people don’t know how hard is to make 60-90 seconds bake pizza taste good and harder to be consistent than longer baked pizzas.
If your high ranked you’re always good? No if your low rank your bad? No way.
To be honest for me Sally’s in New Haven is the best pizza in USA. If you don’t really care deep inside about pizza on dough. It’s nasty bromated flour but who cares it’s crispy and flavor intensity is no match with any other pizzas I had in US
Also if it’s tony, he might know when they come 
and tony can make good pizzas if he try hard. Pretty obvious when you received award couple times you kinda know who is who.
Overall I think high ranked people kinda know when they come and showing their cap level when they visit.
This is a futile exercise, but:
Wonder what the rationale is for Song’ E Napule to drop out of the list this year, from #15 last year. We still liked their pizzas quite a lot, and would consider it our go-to spot, though they have expanded in recent years.
Overall it’s a very useful guide when we travel.
They are going to have 4 location
They are going to move to artisan chain selection this year
I randomly went to their NJ location in Rutherford and it was pretty disappointing I’d say
