The Soviet T-34 was vastly inferior to the German panzers as well.
The T34/76 was considerably superior to any panzer then extant in 1941, when they were first encountered.
It wasn't until 1944 that the Germans reached the point that the overwhelming majority of Panzers were better than the T34/76.
And at that point, the Russians were building the T34/85, which was rather better than the latest version of Pzkw-4 (which was about half the German panzer inventory), though somewhat inferior to Pzkw-5 (the other half).
The only real weakness the T34 series of tanks had was lack of proper communications equipment (only the company commander's tank had a radio, for instance, until late in the war).
Plus that gawdawful commander's hatch on the earliest T34s....
If you feel that technology assures victory where is the Roman empire today?
If you think that the Roman Empire dominated the Classical World due to superior technology, you know even less of history than your comments about T34 suggest.
Hint: the Legions' doctrine was far more important than the Legions' technology (which was basically the same as everyone else's (iron swords, spear, torso armor and helmet) and considerably inferior to that used by the Persian cavalry at the time (yes, I've always been rather fond of the Persian composite bows as weapons of war - it's really too bad the Romans worked out a counter to it).
