There was a fight between a Super Pershing and a Tiger/KT, I believe. In Another River, Another Town, the tank gunner of the said Super Pershing describes a confrontation with a Tiger/KT (I forget which) at close range.

The Tiger in all probability hit the Super Pershing (see article for why "in all probability") but the round glanced/didn't penetrate. The Super Pershing then proceeded to put a round into the underbelly of the Tiger as it tried to traverse a steep rubble pile. Needless to say, the Super Pershing won.
