I asked ChatGPT which was better. Pepe’s or Sally’s.
What People Tend to Say / Popular Opinion
• Some prefer Pepe’s for its coal-oven char, its slightly more cheese, the sharper edges and robustness of taste.
• Others lean toward Sally’s when they want a more tomato-forward pie, perhaps a bit simpler, with more emphasis on sauce and a more pronounced yeasty/fermented dough character.
• In blind or taste-test style comparisons, results are mixed. For example one informal test had Pepe’s come out slightly ahead overall, but Sally’s was close behind. 
• Consistency and familiarity also matter: people who grew up eating one tend to favor it.

My Take
If I were picking, here’s how I’d choose:
• If I wanted bold flavor, a chewy crispy crust, and some of the iconic pies (like the white clam), I’d go with Pepe’s.
• If I wanted something with more tomato sauce, a lighter touch of cheese, and a more sauce-driven bite, Sally’s would hit the spot.
