 Of all three fighters, the Bf 109E would possess the highest roll rate, with the aileron controls being brisk and responsive; the Spitfire had the highest aileron forces, but both the Spitfire and the Messerschmitt's rate of roll suffered at high speed.Overall the differences in performance between the Bf 109 and Spitfire were marginal and in combat they were surmounted by tactical considerations such as which side had seen the other first, which side had the advantage of altitude, numbers, pilot ability etc.with the main difference between the two aircraft being the Spitfire's tighter turning ability and the Bf 109's faster climb rate.
