I tried the volumetric sculpting and I have a hard time with the controls/the tools.
For normal sculpting, they seem to be good, but for non-organic structures they really annoy me at times. For example, if I want to pull the edge of a cube out, that seems to be very difficult. Advanced manipulation seems cool, but the basic stuff is really hard. Also, edges on the "complex primitives" get really weird at times, they're very messed up and not nice and straight. The Complex Primitives video looks great, but it's not as easy as it looks there...
Edit:
Here's what I mean. Maybe I'm just stupid, but this looks disgusting:
