Family from LA come to visit us in Pomfret and Pepe's is always one of their top 3 things to do.)
I never go to WDW and get either barbecue or friend catfish (not that they have that... Lol).
This is kind of like the recent threads about Marylanders with crabcakes and New Englanders with Lobster rolls. If your region excels at something the chances are that it won't be comparable at WDW.
That said, I also live in CT and do enjoy the pizza at Via Napoli. It is the thin crust variety all the varieties I have tried have been delicious. I think it is worth a shot for you as long as you go in with the expectation that it may not be quite as good as what you get at home.
We too enjoyed the pizza at Via Napoli. As Marylanders, we stay away from the crabcakes - LOL
