Talking about Zhukov - have you heard about Seelow battle.
Stupid, unnecessary loses. Anyway if Konev lost more soldiers than Zhukov - it doesn't mean Zhukov was great. Remember that we should compare it with other generals, not only with Russians. We must remember that Russian commanders into WW2 often got big advantage in humans and equipment.
So I don't think Zhukov was superb general - hi simply was well general.
