My vote is the F-86. There are too many Apples and Oranges to compare roles on this list. many of these aircraft were more prominent in the 1960s and shouldn't be on here. F86 was the best aircraft as an air superiority aircraft for its time and the pilots amade the difference.
About a year ago or so Glider and I had a discussion about the Hunter vs. the Sabre and I think on the world wide battle field, they came out about even in kills against each other. The -86 smoked a few MiG-21s over India/ PakistanI agree that most of these aircraft are from the 60's but might give the edge to the Hunter over the 86 only because it came out much later
antbody notice there is not one US Navy aircraft on the list such as the Grumman F11f Tiger ,Panther and Cougar,also missing is the Ouragan and Mirage ll although I wouldn't include it in the best fighterthe F89 and Cf100
The F7U was pretty much a failure. As with several Vought creations it was too advanced for it's time and had many operationl problems. One problem I heard about that was trying to be fixed when I worked next door to Vought at Temco was that when the guns were fired the engine flamed out. I was involved in the flight test engineering of the Temco TT-1. LOL I don't know why the Skyray was not continued in service.
