I personnaly believe that the British severly lacked in terms of tanks and SP guns, with the Germans and Russians leading(even if many German tanks\SP's were just make shift), I believe none of them to be up to the task of taking on a German BattleGroup and hoping to win without extreme superiority(there are exceptions to this), just look at the formation of Shermans, one being the Firefly only supposed to take on Tigers, while the other shermans would try to encircle it and hit it in the engine. During the Nomrandy invasion the allies enjoyed complete air superority and were able to knock of German heavy tanks and prevent movement, which lead to the British to have the upper hand in tank movments.

I believe the Americans were catching up with the German tanks but still did lack until the end of the war.

The Russians, I believe were the only country able to properly engage the German Tanks and expect to win with the T-34's, all the 'T' series as well as the SU. JSU, and the JS series, the Russians T34s was even better then the German Tanks at the beginning.

OK but if I had to chose one British tank I would have to go with all the Cromwell series dispite there flaws, they were are good tank design even if they were lacking.
