Personally, I feel the FM-2 is much better suited to the type of combat we have in the MA, than the F6F. However, the F6F is a far more capable aircraft for strike missions, in terms of bomb load.
I fly the Wildcats a great deal, and I figure I'm a fair stick in them (69 kills, 2 deaths so far this tour). Like anything else, being successful in the Wildcat requires sound judgement and good situational awareness. Actual dogfighting skills take a back seat to "smart" flying, by being able to avoid bad situations where those skills would be severely tested.
You should be able to do very well with the FM-2 with some experience in it. However, the little fighter's lack of speed requires planning and judgement to avoid getting ganged. I suggest setting guns at 600-650 yards, as you will find yourself pursuing aircraft that are pulling away from you.
Should you find yourself defending a CV group from hordes of enemy fighters, jabos and torpedo bombers, don't be ashamed to duck into the ack if you need to. AI ack is the most reliable wingman you can hope to have.
As far as the F6F goes, if I'm taking a jabo or attack sortie from a carrier, I use the SBD, simply because it's so much fun to fly and dogfights with the best of them.
