Depends. If you're going to your standard pizzeria, then Pepperoni. If you're going to a place with a wood oven, a real nice Italian place, or homemade, then it's going to be Margarita. Pepperoni pizza is going to be good no matter where you go. Margarita can surpass it at a great place, but under perform elsewhere.

Pepperoni because I never had margarita. I don't even know what it is.
