FM2 will in theory have a hard time out turning a Zeke, The Zeke however is a lot less benign at stall speed and a less experienced Zeke pilot will likely not be able to turn w maximum AoA without stalling so the FM2 in reality have a decent chance to beat the Zeke.
The nemesis of the FM2 is the Brewster, the Brew have better turn and roll performance than the FM2.
What the FM2 do have is excellent view over the nose, its one of the few planes you can take a near 90 degree deflection shot and actually see your target and its very useful when taking snap shots.
