It seem that the OP is not longer with us. As this is an very important subject cannot some  knowledgeable do some renders, comparing  old figures (that most of us have such as for instance The_Girl_Next_Door_4_Athletic) with the newest and the best. With screen shots of settings. And when we are at it why not also compare against those with high-res photographic material made with Deep Paint or Bodypaint (mec4D and JSGraphics). Then we have this matter solved once and for all.
