German tanks outside the panther and tigers were not brilliant and were equally matched by the allies, also the bigger cats were unbelievably unreliable and hard to maintain.
Russian tanks were just thrown out, the t-34 tank was only good due to the numbers in service and the early days before the Germans up gunned , they got eaten up like flies in battle afterwards with a massive K/D ratio against them.
Apples and oranges, the best tank was of course the centurion, but came a tad too late unfortunately but was well in the design stages mid war I believe and held back to concentrate on existing manufacturing.
