Definitely not Papa John's. It is the loosest definition of pizza. Below even Chicago Deep Dish.
My favorite Papa John's memory (because if you're an American, you've been forced to eat this slop at some point) is we had an On Call shift for NCAA events (I worked at a sports site) so they ordered us pizzas, donuts, salads, the spread since we'd be there until 3am. This was three days after Papa John himself had to resign for saying gamer words. His face, prominently featured on all the boxes, had been replaced by a "Now Hiring" sticker in an inconsistent manner, which led me to believe the employees at the kitchen had some feelings about the guy...
I live in poland and Papa Johns has recently opened a few restaurants here but nobody wants to eat this hyperprocessed trash when the local joints (some run by Italians) are so much better for the same price.
Even local corporate pizza franchises are way ahead of any american ones like Papa Johns, Domino's or Pizza Hut in quality.
I've had lots of good pizza in the US, almost exclusively from independent places that serve NY Slice/Detroit/Neapolitan, and only one from a chain that's even close to decent: Blaze Pizza, which goes for a neapolitan-style in a fast casual setting. That's about it.
