I don't think texturing is more free-flowing and creative. Especially for skin textures. But it's more detail-oriented. Getting things lined up right, and all that.

I'm sticking with Poser myself, but just judging by the posts I see at the various forums - a lot of people are either switching to D|S, or starting with it, without ever hearing of Poser. The whole point of creating and giving away D|S (and M3 and V3) is to increase the size of the customer base for content. V3 and M3 content. I think it's going to be tough to go against that trend.
