It would be interesting to see how the P51 would have faired, or even the F6F.
OK, without googling it up (yet
), the P51 Mustang did indeed have some performance weaknesses relative to its contemporary German opponents that a skilled Luftwaffe pilot could exploit, this becoming largely irrelevant as few skilled Luftwaffe pilots were left by 1944, and the Allies IIRC enjoyed about an eight-to-one numerical advantage in fighter strength over Europe by that point anyway.
I believe the F6F, having been designed in a large part to fight the Zero, sacrificed some speed for maneuverability, and towards the end of the war over Europe at least, speed as a fighter asset was becoming more and more critical.
