Soren, the nagging thing is back to anecdotal stories.
One of my dear friends was a marine Night Fighter that flew F7Fs out of Okinawa at the end of the war. He flew F4Us, F7F and also flew the F6F and F8F. He swore that the F7F was the best single piston engine fighter he ever flew and I have heard this from several pilots that flew the F7F.
It was a 'beast' in a spin (unrecoverable after 3-4), a beast in a dive above .8Mach but allegedly outclimbed the F8F by a significant margin, was faster and could out dive it. Could not turn or roll with F8F.. but I want to see the facts (lol).
And the 'freakin' thing could carry a TORPEDO...try sticking that on a P-51 (or Ta 152)
