In my opinion V4 is more realistic than V3. The morphs are more natural and she is also easier to pose. She is also the future in regards of merchant support. I think it's good to have as many figures as possible to variate your artwork. In regards of clothes conversion, I do prefer wardrobe wizard because it allows morphs to be taken over, respectively to be injected into the new clothing. I also have the Crossdresser but you need to inject your morphs yourself using for example Netherworks morph kits which is more complicated. If you need a lot of figure licenses and morph kits, the price difference between the free crossdresser and WW isn't that big. If of yourse, you don't want to morph the figure CD will do :-) Skin textures can also be converted like mentioned above.. I think V4 is definately worth it...
