When I first starting using ShaperBox, the workflow felt clunky to me (i.e. you have to hold ctrl to create new points inside their plugins; my intuition would tell me holding a modifier key changes the curve or something along those lines). However, the wealth of sound-design features didn't go unnoticed. And, of course, I got used to the workflow.
Now with ShaperBox 2, there's the addition of some really key features that I think a lot of us are going to appreciate over time: the 24db crossover for smoother multiband processing (on par with something like FabFilter's Pro-MB - the gold standard), pens for faster node editing (which could make up for the whole weird modifier workflow thing in their plugins), and the compression section in VolumeShaper (sounds very SSL-esque: nice and glued without too much of a "color").
This is all in addition to the awesome shit you can do with stuff like HalfTime (turn literally anything into a crazy drone soundscape or bass; saves you from feeling you're out of ideas). Basically, yay for the Cableguys Bundle! =D
