Its a very common notion that the Germans were far more experimental and forward thinking than us. They were indeed very advanced, and were cornered into trying out there designs in the metal.
However there where some amazing British designs, prototypes and research that we didn’t really have to try out, probably because we were so sorted with the designs such as the Spitfire and Lancaster. I hate to say it but I guess the modern deigns coming from the States also kept us on a pretty conventional footing (think B-29s versus unpredictable rocket fighters).

At the end of day, the Germans advanced fighter design ahead of us, but lagged behind terribly with bombers.
Gotta love their crazy protos though, who would have been brave enough to take on a unit of Trieblfluges!
