It's already been mentioned, per the same stats, the F4U was hit slightly *more* often than the F6F in apples v apples comparison, but not statistically signficantly. Both were hit about as often, but F6F's survived significantly more often when hit.I think the Corsair was hit less often, so more survived
I think one key issue just mentioned by Renrich was the reputation for effective *doctrine of close air support* by the Marines particularly early in the Korean War compared to the cooperation of the USAF and Army initially in that war. That became a general news sort of topic at the time. Of course we often see events in WWII through the lens of later events and this is one example I think. Marine a/c provided close support to Marine ground forces also in WWII, but it was more of an emerging mission, not the key mission for Marine air it's been viewed as post WWII, and not with the same favorable to the Marines/unfavorable to other services connotation as in early Korean War.
But, even books like "Victory at High Tide", about the Inchon campaign, by Robert Heinel, basically official Marine historian, whose books were dual purpose history and recruiting/tradition building tools, not full warts-and-all histories of Marine operations, mentioned the vulnerability of F4U oil coolers to ground fire.
