Yes, its supposed to be better. The early model of the Corsair was faster, and more manueverable, as well as a more stable gun platform, because, although it had fewer guns, the fuel was still in the wing (Not entirely sire what difference that makes, but according to F4U pilots, it makes it a much better fighter), but, in the later versions, the added one more gun to each wing, and had to move the fuel tanks into the fuselage, which for some reasons reduces performance. Im not sure about the science of it, but thats the what.
