Someone mentioned that turning ability was not an important factor at all. Well, for an F6F with a Spit IX on its tail, that does not quite fit.
However, Speed and acceleration are very important factor, especially if the difference between the two planes is big enough to allow one of them to draw away after some hard maneuvers.
In AH, one is often confronted with a non-historical gaggle of bandits. In such an engagement, turning may keep you alive, simply because you never manage to get up enough pace to get away. In there, the Zeke shines. But 1 on 1 I would put my money on the F6F.
