You can state this argument for every tank in the game. That is the reason why i think the argument is not valid.
Actually, there is fundamental difference between churchills and any other tank in game.
Their speed and maneuverability makes it much more likely for them to just go head on without flanking, because they are too slow for these kind of maneuvers.
You KNOW that churchill will roll right head on, because it can, do some damage and roll out for repairs.
If you can get engine damage on it and have something with tracks to keep up with its slow roll out, you can take it out, served on a silver plate. OKW have it harder, because schu mines can be detonated by infantry, but its not like churchill need inf advancing before it and rely on scouting for AT, because it simply can take a hit.
