I feel slightly ignored ...
On a more factual basis and hopefully on a less bashing tone that settled in a couple of threads ago (it closes in on youtube comment level):
I too think that the Luftwaffe is usually overestimated. It had at the beginning of the war machines that outclassed usually the opposing types. They had a minor advantage in experience and tactics over a short time. This changed progressively with the campaign in the West, where they encountered the more advanced planes that were close or equal in performance and when the pilots gained more experience there. With slower pace the same happened in the Eastern campaign, when initially the Soviet planes were completely outclassed and pilot experience was bad. They cought up later. It ended up in a number game during the last stage of the war.
PS: The German planes lost in Poland were mostly lost to ground fire not Polish planes that had been primarily destroyed on ground.
