Its a case of what against what. Look at the figures the LW achieved in the early days of Barbarossa. Prior to WW2 starting the Soviet Union had more aircraft than the rest of the world combined.
I'm not sure of your point. It may well be the difference in experience -- LW vs VVS, IJN aviators vs inexperienced. Why did the Buffalo turn in good numbers in Finland, and rather weak in others? What advantages were Finnish pilots using that USMC at Midway, or RAF in Malaya, weren't?
