It's really highly exaggerated, both in that show and in popular culture. Nazis would not have travelled to Mars by the 1960s, and they wouldn't have supersonic civilian airliners. Nazism crippled German science, math, and technology. If you remember your math courses, many things have German names. You'll notice that's mainly pre-1933 works. The mathematical establishment at Gottingten and elsewhere, which included many Jews and people married to them, was eviscerated. Ditto for physics. The only place they were unambiguously ahead of Allied technology was rocketry. Our bombers were superior, Soviet tanks were superior to what the Germans had, and the fighters were comparable. Even with rocketry, the allies would have caught up even without Operation Paperclip. Nazism really doesn't have any upsides.
