Germany kit was better than Allied kit, just they had a manufacturing and people resource issue................. losing 10 T34s for every German tank sound like a bad ratio until you have 2000 T34's and they have 100 tanks.
Russian Tanks were no way superior but they just had a hell of a lot more of them.
