F4U-1 from a carrier deck, P-38L for doing ground work. The 5 superplanes will eat both of them alive, so every operation has its own rewards, just don't expect to land any kills.
I'm thinking, though, that what I might start doing is flying the plane that killed me last. That would give me a reason to finally start flying the N1k2, LA-7, P-51D (as a fighter instead of my usual ground attack), Spitfire IX (haven't flown it since my first month here), and FW-190 (or F6F - I see both about as often).
