The Zercher squat was invented by a lifter when he was in prison and didn’t have access to any racks so he had to lift from the floor. You will use lower weights with the Zercher squat because you will find it simply impossible to handle anywhere near your max loads.
This Squat variation builds power out of the hole. The initial awkwardness of the movement forces you to balance in a new way as well.
