I think numbers are important in warfare. After all, Germany did have the technological advantage in WW2 and they lost. We did not have anything that came close to the King Panzer.
They have jet fighters, remote controlled bombs (cruise missiles) and V2s.
Small issues with the the German stuff towards the end of the war: The Nazis were so bound to their system that they ignored or delayed really important technologies while wasting huge amounts of resources on completely useless technologies. Without question, turbojet engines were a leap ahead in speed and altitude performance and would have dramatically influenced the cource of the European war. Despite this, Hitler forbade its fielding until the best aircraft available, the Messerschmitt ME-262, was converted to be a "Lightning Bomber". Wasted (thank Heaven) about a full year before they could employ the thing. They also ignored their best scientists (or chased them to us) who recommend development of a fission weapon. They fiddled around with monster howitzers, ridiculously-oversized tanks (the Maus, the King Tiger, etc.) and those tactically and strategically useless V-1 and 2s whioh did nothing at all to win their war. The US and Britain stuck to the technologies that really made a difference: heavy bombers, long-range fighters, anti-armor rockets, and lots of supremely dependable tanks, medium howitzers, and small arms. They made bad choices and they lost - always a good thing.
