I LOVE the SS/PP dvd much more. You can make them as easy or as hard as you want to, and for that, I turn to them often. They're also just fun.
The other DVD, however, offers three incredibly advanced workouts. Body Max has been my fitness test for the past 10 years. If it's doable, I know I'm doing well!! I just don't "enjoy" these workouts as much, probably only because they're so intense.
I think it completely depends on what you're looking for.
