Okay, I have a realignment of my choices. They are based on aerodynamic performance and combat experience and performance. The justification for the latter is that performance may be misleading, but combat performance is the ultimate test.
First Place. F4U-4. Performance was excellent from SL to Service ceiling, in both airspeed and climb, and had a great reputation for maneuver in all combat situations. Good Ceiling (41.6k ft.). Combat experience: WWII, Korean War, and Soccer War (El Salvador vs. Honduras)
Second Place. Three qualifiers. They have various strengths and weakness, I could not decide an order between them. So here they are in no particular order.
Sea Fury. Performance, including airspeed, climb, and maneuver, was excellent at lower altitudes (I have limited data to support this performance assessment). Mediocre Service Ceiling (35.8k ft.). Combat experience: Korean War. Low Service Ceiling and limited combat reduces selection level.
Ta-142H. Performance, including airspeed, climb? (no data), and maneuver, was excellent from SL to Service Ceiling. . Excellent Service Ceiling (48.5k ft.). Combat experience: WWII. Very competitive to F4U-4, lower performance at lower altitudes is offset by high altitude performance. Very limited combat experience and lack of data reduces selection level.
P-47N. Performance, including airspeed and maneuver is excellent from SL to Service Ceiling. Climb is good. Very good Service Ceiling (43k ft.). Combat experience: WWII. Performance similar to F4U-4 with emphasis on higher altitude performance. Lower combat experience to F4U-4 reduces selection level.
Honorable Mention:
P-51H. Faster than the F4U-4 at all altitudes, good climb performance (slightly less than F4U-4), good maneuver performance. Good ceiling (41.6k ft.). Combat experience: None. No combat experience negates rating.
F8F. Excellent climb and maneuver performance. Airspeed is limited. Good Service Ceiling (40.7k ft.). Combat experience. French Indo-China. Lower airspeed values and small combat experience reduces selection levels.
Others, probably.
