I'm comparing planes not pilots. The wing area of the Hellcat was the largest of ANY WWII single engined plane.
The piss poor production numbers of FLYABLE Nik2-J's do not even allow this fighter to "hold such a title". Japan chose to start it, they paid in spades. They banked on "nimble, fast, tight turning, unarmored cockpits and un-sealed fuel tanks" on almost every plane, and it was their undoing. The US had superior planes to counter ANY Japanese plane produced.
