I have both and I hardly ever use Stephanie 3. There is really nothing that it can do that can't be done with Victoria 3, and it is disappointing that there are less morphs in the S3 morph packs than there are for V3. And I don't like the way S3's legs look as compared to V3. Plus there are a lot more clothes and other things out there for V3. In general it is just easier to use Victoria 3 and I get better looking results. I sort of get the idea DAZ cam out with S3 just to make a little more money by having you buy basically the same thing all over again. Save your money and use it on something else. My opinion, of course.
