The Germans had two innovative designs in production during WW2 that had no allied counterpart: The V-2 ICBM and the V-3 stationary supergun. But even for those two technologies, the Germans stole the V-2 hook, line, and sinker...right down to copying American professor Robert Goddard's gyroscopic control and engine venturi...and the V-3 was simply an electricly-triggered version of a pyro-staged American Civil war cannon.
But for everything else, the allies had the same or a superior version. For the German V-1, the U.S. had the JB-10. For the ME262, the U.S. had the P-80.
Where the Germans fell remarkably short, however, was in the areas of mass production, encryption, computers, and atomic warfare, all of which were dominated by the U.S. and UK.
Moreover, the illusion of German technology is primarily due to the fact that the Germans lost the war and had **all** of their top secrets exposed. In contrast, the U.S. was able to maintain its secrets (well, except that the atomic warfare was a bit hard to hide, and the field of computers was so eagerly being pursued in U.S. research centers).
