It’s the pilot, the training and the experience, not the plane.

“It’s the pilot, the training and the experience, not the plane.”
Like being a professional bowler and using a house ball.
Don't forget motivation, the willingness to get into the fight, of which the Polish pilots had plenty. A pilot can be as trained and experienced as you want, and can have an excellent plane. None of that matters squat if he refuses to engage.
Look at the Iraqi pilots at the start of the first Gulf War, who fled to Iran rather than face US forces.
