F4U-4 by FAR the best of the Hogs. In fact, she's just about the best all-around fighter in the game PERIOD. She carries a bit of a perk price, but for dammed good reason. Outclimbs, outruns, out accelerates every other Hog. Best vertical. However the engine is a gas guzzler, and IIRC she carries the smallest internal fuel load to begin with.
I have to put the 1A next. Faster than the 1D and 1C by about 50mph, and does pretty much everything better than the -1 except generate perks. Excellent endurance. The most maneuverable Hog (even better turner than the -1, and will beat it in the vertical). Still not exactly sure how she escaped a light perk (5-15) but I won't tell anyone if you wont.
Next 1D. Probably the best jabbo of the bunch due to the extra pair of rockets. Better climb and acceleration than the -1, though slower and sacrificing maneuverability to a limited extent. Shorter range than the -1 or 1A, but greater than the 4.
1C fourth. Although the cannon pack a punch, she lacks the ordinance loadout of the 1D so while a good strafer, isn't quite as effective as a jabbo. Also, the weight of the cannon are noticeable, as she's the slowest and least maneuverable Corsair (that being said, all five are close enough that the difference is really rather insignificant). The best vulcher, and the 20mm will generally discourage most HOers.
1 I would have to rate last. She's tied with the 1A for speed (second on the list, or a very close third with the difference being practically insignificant) with I think a slight advantage in range--fuel distribution IMO leaves something to be desired, though. However all-around visibility is poor, and especially at low speeds she feels VERY heavy and sluggish. Acceleration and rate of climb are rather poor. She's a perk farmer though, and has the highest ENY of any Corsair.
