Load of crap. The T-34 was a piece of junk. The only redeeming features were the Christy suspension and the fact that the crew and motor could be swapped out quickly after they were dead. Russia had lots of them and Germany could not compete with the numbers, same with the Sherman. Sherman crews were known to abandon their tanks when they sighted a Tiger without a shot being fired. German armor was far superior but far too few to stem the tide against the Reich.
Guderian disagrees with you and said the T-34 was much better than the German tanks. Speed, mobility, simplicity, reliability and firepower were all there.
It’s not a big dispute expect for those who think everything Germans made was superior
