No homo, I can squat my ass off. Always had big quads naturally and don't need much to get much. Squats are ok but I got alot more out of front squats. I guess it depends on how you're built
that is true for everybody
it's simple
the more upright your torso stays in a squat the more knee extention dominant the move is
the more forward the torso, the more hip extention dominant the move is
because of this the stresses shift to the most dominant hinge point
so a back squat (and even more so a low bar back squat) will build the thigh close to the hips
and a front squat will build the thigh close to the knees
