Powerlifters use the low bar position because it allows for greater weight and less torque on the lower back. If squatting higher weight isn't your goal there really isn't a reason to do them. Personally, I've found that the front squat helps develop the quads better than the back squat. word, ive started doing front squats and i love love love them. i do them after deadlifts on a different day from my low bar squats though; i can't see how people do high bar. I feel like my neck is gonna break. front squats do hit the quads more directly; however i actually feel my back a hell of a lot more during front squats than low-bar back squats.
