Front squats use less weight, and shift the weight much more to your quads and upper back. It's kind of how the press and bench alternate on SS, you use less poundage on one lift and that facilitates the recovery.
That said, if you're not interested in oly lifting or learning a new lift, you should just back squat. If you want to do something different and help your oly lifts, try front squat. Personally I'm going to try the front squat just for variety.
