I have the set you are talking about Bubbles - I also requested it for my birthday a couple of years back. I haven’t tried any of the others you’ve mentioned except Cathe’s turbobarre, so I cant compare it or really answer if it’s worth it in that manner. But I can say I like this set. I happen to really click with Suzanne. I love her demeanor and cuing. Her stretches are amazing. I like cardio fat burn and boot camp because they do add a little cardio factor to the barre. The workouts are long, but are all sectioned so you can just choose which sections you like. I really like her Tighten Tone and Torch and feel like these are somewhat similar to that, if you’ve ever tried that.
Being a vf’er, naturally this conversation makes me think I need flat belly barre.
