Favorite Major Pizza

There are over 70,000 pizzerias in the U.S. alone. However 61% of all pizza sold in the U.S. comes from the "big four" chains- Papa John's, Pizza Hut, Dominos, and Little Caesars. Which of the major big four chains has the best pizza?

I don't count any of those listed as providing, "pizza". Pizza to me is puffy crust with a very airy and light texture and yet density, with a substantial load of cheese on top.
