Only once they added the three-man turret with the 85mm gun. Before that it was average to slightly below average for it's time. It's just that the rest of Soviet armor was so much worse. But the early two-man turret was a pig to fight - having the TC be gunner is always a bad idea - and negated most of the advantages of the rest of the design.The T-34 was one of the best tanks of WWII imo.
