I live in Rome and I know some pizza directly quoted in the article.
I would say that in Italy there is not just the pizza Napoletana (the Queen of Pizzas!), But there are also other types, some very different from the Napoletana
In Rome there are at least two:
a) the "pan pizza Roman Style" (it is sold in pieces and is very very soft and supple, has more than 90% moisture and is very difficult to achieve. It also eats stuffed with mortadella. yummm).
b) Roman Style Pizza served on your plate. It 'very flat, without cornice, crunchy.
To me the type b) do not like.
Instead the type) is very good (IMO) and the addresses mentioned in that article are correct: Sforno and Pizzarium are two good pizza, I highly recommend you.
In particular Pizzarium is considered by so many as the king of pizza pan (and perhaps this is a bit 'too).
The others I know only by name. 00100 is like Sforno (I think).
I hope this helps.
I must also say that the pizzas that I see in this forum are actually WONDERFUL and definitely deserve the same dignity as those of professionals.
