I've been researching/reading about WWII flyboys and I've come to the conclusion that the Germans were better pilots. Mostly because they were required to fly quite a few more mission than their American counter parts.
That was a double-edged sword.
It was great, as Germany had many 100+ victory, highly experienced and skilled combat pilots that had served since the Spanish Civil War, throughout the war.... but combat pilots die.... period. And since they were never cycled back to train new pilots, like old pilots were in the US and UK, new pilots arriving at the front by 1943, 1944, and especially 1945 were
extremely under experienced, with Germany's 'Alte Haeren' running thin... by 1945 you had entire Geschwaders of new, under trained recruits (though with the USAAF bombing campaign you'd think the Luftwaffe would be short on planes, but in actuality many planes were not used period due to the lack of pilots and fuel), supplemented by a handful of pilots who had been around since the Battle of Britain, facing hordes of well trained pilots whose training was supplemented by pilots who had 'been there'.
i believe i read(again) that luftwaffe pilots trained in gliders(before the war) before they were allowed to touch a powered aircraft. this would have gone a loooong way to teach them energy management.
This was a hobby of many of the more successful pilots, I've never read that it was part of any kind of training though.
