Just to tack onto what others have said, you are right to have the suspicion that the NSDAP supporters (as we officially call the WWII "Germans" here in Berlin) well known notions of cultural superiority carried over to the belief in their equipment types compared to what they perceived as their historical "Slavic" enemies prior to the invasion. However on the Eastern Front this only lasted until the Autumn of 1941, when designs such as the T-34, KV-1, and other such sophisticated inventions made it abundantly clear that Soviet equipment could be useful when needed.
