I agree on your points Batz, as long as you are not falling into the trap of quoting the top 5 percent of the "aces" scores to prove your point. Aces scores are way too often used as "proof" that "plane X" was this or that. If you know what I mean.
As for the IL-2, it may be a victim of pilots who fly it for one way missions in the MA as opposed to being weak. IL-2s attacked all sorts of "softer" targets in WW2, troops, trucks, ships, depots, AFVs of all sorts, they didnt spend a lot of time attacking Osties directly in RL. Also, they were used en masse.
