If I had to pick one and only one I would pick the P47N, no other aircraft has the ability to carry that much ord, and manuver like it can once it has dumped even half it's ord and has that great a boost is speed with WEP, that many guns, and the ability to carry enough fule in drop tanks to operate soley on so you can carry 25% in internal tanks so you can get home and dump the tanks to pick up more speed, reduce drag, increace manuverability, AND take as much damage as the P47N ALL in one package, not even close. But other than that it is P51, P39, F6F, and P38.
