High bar squat focusses mostly on the quadriceps.
Low bar squat allows glutes, hamstrings and especially lower back muscles to add to the quadriceps. For this reason, low bar squat yields the highest possible raw squats.
Powerlifters are the only one using it, cause for powerlifting only the weight you can squat matters. We are the epitome of squat.
The high bar squat might appear more "natural" but its flawed and not as much of a compound as low bar squat. The ROM argument is wrong. The competition rules say "below parallell". It means its unneccecary to go lower, wich will cost you power, but it doesnt mean you cant.
Every worldclass raw or IPF equipped squatter, does pauze squats frequently. Wich is pauzed at the very bottom. There is no difference in rom.
Because olympic lifters are exceptionally agile in the bottom position, they seemb to go deeper, but its simply a demand of their mechanics.
The olympic weightlifter argument is also wrong. The reason they practice highbar squat is because of the mechanics of snatch and clean&jerk. For maximum yield, your upper body must be able to dive under the bar as fast as possible, and this can only be done with a vertical position. High bar is vertical, low bar is at an angle.
If you want general strength and a bigger squat, squat low bar. If you want stronger quadriceps, do front squats. If you are an olympic lifter you do high bar squats.
If you are anything else, do high bar, you dont have the back for low bar anyway.

I do fucking hate however, how these fatass american multiply freakshows are giving powerlifting a bad name, especially considering ROM.
If you see a morbidly obese fatass standing with his legs extremely wide, in a big black suit, wel thats multiply. its the synthol of powerlifting. Everyone hates it apart from the handfull of idiots who do it
