The answer to this question largely depends on personal preference. Chicago-style pizza is characterized by a thick, buttery crust, filled with cheese and topped with a chunky tomato sauce, and is more like a pie. On the other hand, New York-style pizza features a thin, crispy crust and is usually topped with a thin layer of tomato sauce, cheese, and a variety of other toppings. Both styles have their passionate advocates and are unique in their ways.
