very little to no aero difference between them. I prefer Mcalister bodies. They are very lightweight compared to others and they have excellent durability. I don’t run any shoe goo or tape on mine. Any handling difference that may exist between the bodies would come from the difference in weight. With the Mcalister being as light weight as they are, I can put the extra weight needed to get to legal weight low on the chassis. My body only weighs in at 105g with an actual paint job on it instead of doing the BS translucent one color with no decals crap I see others doing.
