Top level Olympic lifters have less difference between max front squat and back squat, this is exercise can have benefits especially if your lower back gets tight from doing back squats. The problem with front squats ( clean grip) is that they put a lot of stress on your wrist.
From memory I recalling reading research on EMGs (Electromyography) data & joint kinetics measures on front squats & back squats which showed greater activation of lumbar muscles ( back squat) & greater comprehensive forces on the lower back and knee.
Back squats load up your knee and lower back more, however you can lift heavier due to greater mechanical efficiency.
