Two late comers into the piston-engined fighters' arena. Both were fighting in Indochina in the French AF; not as fighters, but as ground pounders. What one should be regarded as a better combat aircraft, while putting aside the carrier compatibility of the F8F? The contemporaries would be the P-63C and F8F-1, and, maybe, P-63E and F8F-2. The P-63A was in service in ww2, unlike the F8F.
