Is T-Tapp comparable to CS or Barre?

[TinaT]

My neighbor is moving and just stopped by within the last hour to give me some T-Tapp workouts she doesn't want anymore. I have never thought of trying T-Tapp. I kind of considered it to be similar to CS or a barre type workout.??

She gave me:
Fit & Fabulous in 15 Minutes Book with DVD
T-Tapp Tempo 2 DVD
Yes, You Can T-Tapp DVD
Barefoot Basics+ DVD
Healthy Hormones Brain-Body Fitness DVD
Total Body Workout w/2 DVD
Basic Workout Plus w/1 DVD

4 of them are new/sealed. The others don't appear to be used much.

Who has had good results using this method? I like my two seasons of CS I own and when I'm in a Barre mood, I reach for Suzanne Bowen. Am I missing out on anything with T-Tapp?

Thanks for helping fill in the blanks.
