Churchill, it sure has it's place imo. Compared to the Sherman it can take much more of a beating.
Not sure I agree with this. I'm no expert on it, but as far as I can see from Wikipedia and the in-game performance, most models of Churchills don't seem more protected than a Sherman. It's only the Churchill VII that has really thick armour, and that's 290 points, where a Tiger costs 300 if I'm not mistaken.
Also the Sherman is faster and seems to spot better. And you get a 75mm gun instead of the little 57mm popgun on the Churchill.
