L/W lost BoB for loads of reasons, all of which have been well argued previously:-
1. Hitler insisted on fighters escorting bombers closely at same altitude ie without height advantage.
2. British Radar.
3. Change in German target priority from airfields to London, just when airfields were almost on their knees.
4. Home advantage - Brit pilots bailing safely were reused, L/W bailed sent to Canada & died listening to Leonard Cohen (unverified by WW2 sources).
5. Bf 109 short range - 20mins combat max over UK.
6. German over confidence in ability of Bf 110 and Ju87 which performed well in mainland Europe Blitzkreig, but suffered badly in BoB against decent fighters, well organised.
More to do with tactics and strategy than plane superiority. Interestingly Hurricane (clearly inferior to 109) was highest scoring UK fighter, above Spit.
