I really like S,J&P. It may not be as difficult as Cathe's other circuit workouts, but it's one of her most fun. Plus, it's on the same DVD as Step Blast, which is a must. The DVD has so many great premixes that I find I use it quite a bit. I espcially like the different cardio only premixes. It's also got one of the best ab sections (second only, in my opinion, to the abs in Muscle Max). I'd get it.
