I think a sherman tank would be better.
For every vehicle you suggest the game should have, you have to consider that it WILL NOT make the current vehicles out dated. It has to be contemporary, better in some ways, and worse in others.
The Sherman would have a smaller gun, lighter armor, but better speed than the Panzer IV-H. Perhaps even a better AA defense with a .50 cal M2 on top for the commander.
Still, if you really want a good American tank there is the improved M4A2E8-76 The -E8 means it has a different suspension and the -76 means it has the high velocity 76mm gun.
A T-34 would be nice, but should be a 75mm armed one, not the 85mm gun.
Any stronger tank should be a perk vehicle.
