AGREED! No doubt it comes down to the pilot in this sim. You can go to the 104th's server (as one example) and you'll find the better pilots get the majority of kills no matter what aircraft they fly or fly against. There are a number of pilots that fly the F15 only and they too are exceptional against a less skilled pilot. As it has been stated, you need to understand your own strengths/weaknesses as well as the aircraft's strengths/weaknesses. Additionally, and just as important, you need to understand the strengths/weaknesses of your opponent's aircraft. Air2Air is frustrating, as well as enormously satisfying to learn, but never master. I wouldn't blame the aircraft.
