Take advantage of the squat by doing both in a workout. Keep the sets to 2-3 each. With the front squat, raise the heels on a 2X4, 45lbs plates, etc. More focus will be put on the lower quads (teardrop affect..always impressive).
The front squat is an exercise that requires learning how to do it at first, but well worth the effort. Main problem tends to be the flexability in the shoulders, wrist and keeping the elbows high during the lift, for most BB'ers. After a few workouts on the front squat it will become more natural to you. 300-400 rack front squats, in a lot of heavy duty gyms, are common. Can cross the arm's or just rest the bar on the front delts (may need some extra muscle in the area though for padding) after getting use to the movement. Seen some Olympic lifters do over 500-600 off a power rack. (If you can do 350 pound squat ceans in a regular workout you are indeed a man)
If you seek adventure (and some outstanding legs) than you might add BB Hack squats to any leg program. A favorite exercise of mine, consider it a reverse DL with more attention to the quads than the regular DL. Putting a 2X4, etc, under the heels also direct's more focus to the lower quads. Like the front squat. Good luck.
