We have seen this before. The Jap Zero was a superior maneucering aircraft even at the end of the war. But the Hellcat cleaned them out not because they were better at dog-fighting [they weren’t] but because of superior fire power and much better sruvivabiity. Hellcats came back from battle all shot up, but survived. Zeros didn’t come back.
Same goes with the German Tiger tank vs. the Soviet T-34 tank. The Tiger was more powerful. It was also more expensive and less reliable.
In some actions only 1/3 of the Tigers present were combat-ready. Tough to win a war when most of your tanks are in the shop.
Just to adjust your history presentation, the Hellcat (and the Corsair) had over twice the horsepower, excellent high-speed maneuverability, armor, self-sealing tanks, and excellent pilots coming out of our superior training system.
The Zero had excellent range and low-speed maneuverability, exploded when hit, and experienced heavy ailerons above 250 knots in a dive.
Cold meat for the Hellcats and Corsairs as long as they weren't sucked into a slow-speed, maneuvering fight.

Am not seeing your argument (which is a winner, btw) in the point Gaetz was making.
