Bf-109s might have lost their dogfighting edge by the G-6 model, but they were still highly potent, especially the late Gs and K-4, which could more or less outclimb and out accellerate any other piston engine fighter except perhaps the Bearcat and Pfeil.
Looking back in time, for a piston aircraft I would want a platform that would 1) survive a surprise encounter at disadvantage and get me into the fight then home, 2) initiate a surprise encounter with advantage and firepower for swift kill, and 3) flip air and ground roles when called-for without compromising either. It had is limitations, but skillfully employed, your best all-around bet for mission accomplishment and survival may have been the late model Jug/P-47, except of course you couldn't stick one onto a carrier. Now I've done it, finally entered a "best" discussion. Blech.
