Which chain has the best deep dish pizza?

[Me]

Between Domino's, Little Caesar's, Papa John, and Pizza Hut, which has the best deep dish pizza? I've had Pizza Hut's several years ago, and it wasn't any different from their hand tossed. I'm from Chicago, so I'm a little spoiled, but now that I'm in the south, I'm making do with the chains. Which is the deepest, and best flavour?
Cici's is disgusting, especially for a vegetarian, and I'm eating at home. That's a stupid answer, just so future answerers know.

Pizza hut I would say. However Papa Johns has the best Garlic sauce ever. Omg is it good! But by far I would go with Pizza hut. Its not Chicago pizza but its still good.
