Andy was the one who told me what a waste of time above the knee rack pulls were for helping your pull from the floor.
All this above the knee pulling actually started with Dante of DoggCrapp, in terms of popularity. I know why that he chose that movement, as anyone that has slaved over above the knee pulls knows how sore it will make your traps. So from a bodybuilding perspective this movement might be ok for you in terms of thickening the upperback, however good old shrugs and rows will do the same. But from a powerlifting standpoint it has almost zero merit. And before someone brings up Steve Goggins, don't use exceptions for the norm.
Anyway, its an ego exercise. Leave your ego at the gym door and concentrate on doing things that will make your training more productive.
