Could you explain in what quantifiable quality German tanks were the best-in-class. You mention performance but German tanks were not the best for mileage, ease of repair or survivability, which make up the holy trinity of tanks: firepower, protection and mobility.

Firepower is also arguable, plenty of Allied tanks could engage German tanks at comparable ranges. For example, after the war, the Soviets tested their tank guns against German ones and concluded that they had similar performance and penetration. Also, in the beginning of the war, the Soviet T-34 and Kv-1 outclassed all German tanks of the early war.
