If you're not from Chicago, then you just don't get it. Sorry.
I grew up in Chicago, and my favorite pie, far and away is Chicago-style deep-dish. Living in Phoenix, I try to get it at least a few times a year, although it's hard to find a place here that really gets it right. Rosati's comes close, as does Oregano's... but it's not the same.
That said, I also do enjoy pizza in just about any other form, including New York style, but it doesn't satisfy me like a good thick slice of Chicago-style does. Never will.
I don't get the hate on Chicago-style.. it's tasty, whether or not YOU consider it "real pizza".
