This s a fascinating "russian MG" topic.
Anyway, using the principle that the tank had be in action not just manafactured, by date which are the best tanks of WW2.
my choice is PZIII, against polish armour, Matilda 2 Against the PZIII, T34 against PZIII and IV. T34 Tiger 1, T34 85, Panther, JS2.
I am assuming the T34 didn't see action until Barborossa and that the British Centurian didn't see action.
Would like to include the Sherman, but It caught fire to easily, crew comfort and ease of maintainance is one thing, frying the crews is another.
Feel free to argue, I know you want to.
In defence of british tank design, pre war, they were all built on the cheap and had to fit on the narrower gauge brit railway. Hence small, cramped and horrible. The Matilda is a masterpiece of design when this is considered.
