I voted for Bf109. The 262 has its obvious merits, but for reasons outside its control its overall impact on the war was negligible.
The Bf 109 however appeared when the Gladiator, hell even the Hawker Fury II, was still only on test! This cantilevered monoplane with its 300mph plus potential frightened us to death. It was a signal of Germany's intent, and it was why we had the Hurricane, Spitfire and all the investment and expansion that went hand in hand with them in the second half of the 1930's. Yes we talked of appeasement and treaties, but thanks to this and its ilk we were making sure we prepared for war, thankfully.
