I think it depends on what type of fighting.....to advacne or defense. And what about the brietkiel ? how do you form your attacking wedge ? Tigers at the front followed by Pnathers and Pz IV's and then stug's. Tigers best displayed their efforts in the defensive role as in Normandy where they ruled the battlefied. SS Schwere Pz. Abt. 102 destroying more than 225 armored vehicles alone !
Then on the other hand the Königstigers of SS Schwere Pz. Abt. 503 destroying more than 450 Soviet armored vehicles from January 45 till the fall of Berlin. Not bad for less than 45 heavies I would say ? !
