Most fun Tier 4 and Tier 5 tanks?

Einzelganger7: I do not play tier IV buf trom tier V I have to say my favorite is the StuG III ausf. G. It has really amazing accuracy for the tier and the 150mm  AP penetration is good enough to even make this TD into a vehicle to farm credits if you do not own a premium tank, so that is a bonus even if you are not looking for that as the main factor.
