The problem with VWD is that it's complex, produces inconsistent results, and its features are optimized for DAZ Studio rather than Poser. Mind you, I use VWD frequently, and I know that Herve is working on a new update.

But you have a point. An old python script delivers better results than Poser Cloth.

Here is the same pose using the P13 cloth room. It's not perfect, but I could fiddle with the morph brush to fix the minor issues I'm seeing.
