As someone who has called in both for close air support in a combat situation,I can tell you the AF pilots are the ones you want if the enemy is close enough to see the color of their eyes,and are calling in gun or bombing runs "danger close". Not because all AF pilots are better pilots than Navy pilots,but because AF pilots train for close-in air support (bombing and cannon runs) of troops on the ground,and Navy pilots training is primarily stationary targets like buildings or bunkers.
You take what you can get when you need it,though,and are happy to get it.
My personal preference was for the old A1E Skyraider prop fighter planes,though. They could fly slower than the jets,making them more likely to put the bombs and cannon fire where it needs to go,plus they carried a hell of a lot more ordinance than the fast movers.
It was definitely "pucker" time when the pilot told you to keep your heads down because he was making a Napalm run,though,regardless of his branch of service.
Having said all that,I am not aware of even ONE single instance of the Navy pilots being call on for air support,and not coming as quickly as they could get there.
LOVED Cobra gunships most of all,but when you were in danger of being overran,your prime concern was to call out to whatever could get to you the fastest. EVERY other consideration came in a distant second.
