Buckytom, I don't eat KFC very often (not one in my town), but when I did live in larger communities that had several outlets, I also found that the neighborhood where you bought the KFC mattered, as well as the time of day. Ironically (or not so), the poorer neighborhoods had the better KFC. I'm not sure what that means. But in Hawaii, Virginia, and Florida, in the times where we lived in those locations, we lived "in between" and could go pick up carry-out at a neighborhood more poor than ours, or one much more upscale, and the former had much better quality; better crust, etc.
I, like some mentioned, am not that big a sandwich eater. Yes, I get the point of eating two pieces on bun isn't any worse than eating two pieces with potatoes or biscuits or corn, but it just seems like too much to stuff between bread. Part of it is just me .... I'd buy the two pieces and skip the other starch, the batter/breading on the chicken is enough for me. Another thing is I have a problem some don't. Mom and husband say I take after Dad ... sandwiches fall apart before I've gotten three bites in. So, since I only get fried chicken a few times a year, and KFC only every year or three, I'll stick to the chicken pieces!
