Hi,
As for the whole "Best tank" topic, I think of
the tanks as sorts tools. You bring the best tool for the job. What to root out infanty? Bring OT-34s with Canister rounds. What to knock out scores of tanks? Get an Elite JagdPanther. Nothing is really a "catch all"
Yes, but tank is a very expensive tool and it should be only in a right hands. I will not give my expensive Black&Decker drill to 13 years son of my neighbour.
At the beginning of war Germans easily knocked out excellent T-34 and KVs, becuse Soviet tankers have not a good combat experience.
On the other hand an experienced infantry veteran can easily destroy the tank using the hand anti-tank weapon. Even the flammpanzer cost 2 cents if it will come into an enemy trenches without the infantry support.
Cheers,
