I think they spike their sweet tea with crack.Chick-fil-a might as well print money in Oklahoma. They always have cars in the drive through and their serivce is unmatched. Near my house there is a Chick-fil-a next door to Popeyes. Every Chickfila I have seen in a 100 miles is always busy 6am to 10pm. The popeyes is never more than a couple cars in line even at lunch and dinner hours. When they brought the sandwhich back a couple weeks ago. First time I have ever seen a popeyes with cars backed out of the parking lot into main drag by my house. It lasted 1 day exactly. That is 6 days a week at CFA from 11am to 2pm and 5pm-7pm cars around the building and out into the street.
As for the sandwich they are two totally different sandwiches. Both have their place and are both tasty but really they aren't anything alike.
On a side note I would take CFA sweet tea in an IV that stuff is like crack.
