The Bf109 shot down more aircraft than the Hellcat and Spit combined. Therefore it was a better aircraft and won the war single handed. Oops no it didnt impact is not measured by statistics. No Hellcat and US Corsairs, Wildcats and P38s still stomp on Japan. No Spitfire (backed up by the essential Hurricane) and Germany might get to stomp on Britain, if not full defeat then Britain gets to be a vassal state and signs her life away. No Unsinkable Aircraft Carrier, no Fortress Brittania, no invasion of Europe and a new Dark Age spreads over Europe it might be under a Swastika or it might be under a Red Star who knows. Whichever flag Europe is doomed.
And in that case, France is either speaking German or Russian today...
