I'll not argue with that. However, I think the improvement in performance over the Hurricane is more important.
I haven't looked them up but I'm sure that the Bf109E had a better rate of climb and higher ceiling that both British fighters. If that is correct the scrambled British fighers are going to be higher than when they meet the Germans who will be lower. That would reduce the height advantage that the Germans often had.
Another advantage the British had was American 100 Octane fuel, assuming that the necessary modification of the engines, in the Messersmith over the Sturm and Feuerwind (probably terrible guesses at the German names for Hurricane and Spitfire) will be able to get a power boost in combat.
