The oven (construction, fuel type, how it's prepped, temps, etc) is a huge factor. I've seen a few in BA somewhat like that in Italy. But it's only one factor of many, of course ingredients and skill being large ones. I'd venture to say, like much of cooking, pizza is a science, art and even a spiritual affair. Honestly, I can in my opinion taste the difference when the same pizzaiolo elsewhere making my pizza has a good day or a bad day; it's an emotion they put into the manufacture, imho.
By the way, not surprising but the pizza in Napoli is just mind blowing and I understand why. It just happens.
Also BA is naturally not Italy. Despite the immigration, times, dedications, attitudes, situations have changed.
I go to BA for other reasons so it usual does not disappoint in those regards. I stopped eating pizza in BA, it's just not worth the effort. I save the pizza eating for elsewhere. In Argentina it's other foods for me.
Just my .02 cents.
