Both brilliant, Mustang would not have the combat record it held by being overrated and its range made it a true winner for the job it set out to do, Spitfire held its own against brilliant fighters whilst being outnumbered during the BOB, and always had phenomenal turning performance.
Love them both.
That brute <<<<< on my Avatar btw had a wonderful combat record, and isn't talked about half as much as the F4U.
