Which is faster, Spitfire or Mustang?
Mustang, easily. Similar firepower, more ammo, double the range. The Mustang was 50MPH faster on the same engine and could give or refuse combat at will. If a Mustang pilot doesn’t like the situation that presents, he can leave and there’s little the Spitfire can do about it. Spitfire: Poor energy retention. Poor high altitude performance. Engine overheating.
