yeah about that catching on fire thing...
anyways, it's not really the point about which tank is better 1v1, because there were dozens of shermans for every tiger.
when the panzer 7 was being produced, german design and manufacturing standards had dropped significantly, and as a result, most of them broke (or got destroyed in bombing runs) long before seeing action. Overheating engine, blah blah blah.
And the tiger ace doesn't actually exist outside of company of heroes.
