They’re not exactly the same market—Chick-Fil-A is chicken sandwiches which Popeye’s didn’t have until recently, and I don’t know if KFC ever did. And Popeye’s and KFC sell fried chicken pieces, which Chick-Fil-A doesn’t. When I’m in the mood for fried chicken, I’m usually not after a sandwich.

And I’ll agree that Chick-Fil-A is good, but I think their biggest selling point is their customer service, not their chicken.
