OK, with all 10 listed now...............
The Corsair and Thunderbolt were pretty much the cream of the crop. They of course did ground attack better than most dedicated designs which was one major reason the Thunderbolt was considered significantly more useful than the P51. The P51 was really a one trick pony, long range escort. Most of the top fighters were simply faster and relied on boom and zoom, so dog fighting ability really was just for pub arguments (like this one).
However, during the later stages of the war all the major contestants were tried against each other. And of course, advanced training flights often took advantage of 'chance encounters' between flights of different types. The P47s reputation was saved by these. The Corsairs reputation was made by these.
In fact, when the Corsair was being worked up, one of the squadrons published the times they would be in a clear zone 'training' and invited other services squadrons to come do some co-ordinated training. They whipped butt all the time.
If I was choosing what to fly for:
Fighter v fighter. - Corsair, no question about it.
Ground attack. - Corsair, no doubt about it.
Being jumped, out numbered and just wanting to make it home. - flip a coin, either P47 or F4U or F6f
Wanting to feel cool. - Climb in the rack and get some much needed sleep. It was war after all.
Wanting to seem evil - to whom? During every war it was in, the Corsair was the enemy's worst nightmare.
