Hmm, WWII was a six year long conflict here in Europe, but all this hassle is about Überplanes and porked Überplanes of the 44/45 period. The controversial ones are exactly those which were already modelled in early sims like Aces over Europe. The novelty of Il2 back in 2002 was that it featured earlier planes and battles 'forgotten' in earlier sims (made mostly for the American market).
Now that we have access to the best equipment available in WWII, the everyday 'traffic' with normal cars has transformed into a Sunday Formula 1 race where each pilot wants his preferred mount to be even further finetuned. Only in the best plane can you become/feel the best pilot, so it goes, particularly online.
But after all, it's only a game, and the real fun comes from the successful adaptation of our skills, which are rather limited in view of the fact that most of us would have never qualified as a real-life war pilot, and therefore the historical reality as an argument is always a bit problematic in the context of a sim (immersion is only the illusion of reality). What really matters is that the game challenges you to learn how to fight an illusionistic Dora in an illusionistic Pony, a Hurri in a Macchi, or a Brewster in a Rata (which latter ones I personally find much more exciting

).
