Genesis is okay. I wish I could have M5 as a stand-alone figure, as I will concede that in many ways he's a decided improvement over M4. But DSON is a pain, Genesis doesn't fit my workflow well, and I just haven't invested in enough clothes to make it worth it--not to mention that the clothing I have attempted to use doesn't seem to always work well. So I'm very happy to stick to Gen4. The Genesis Young Teens interested me, but they're overpriced and look too toonish. I'll be interested to see K5, but since so far M5 is the only figure (?) I can call a distinct improvement over its Gen4 counterpart and DAZ never spends much time on the kids, I'm not really expecting much.

 As many in here have said already, it's whatever works for you. I have seen some lovely renders using Genesis. I've seen good renders in DAZ Studio, Poser, Vue, Cararra, Reality, etc. It's not about what tools you use; it's about the artist using them. We all find the tools that fit us best--for me (and a lot of other Poser users) that's Poser and Gen4 (or newer Poser-specific figures like Anastasia, Miki 4, and Tyler--none of which I've been able to use much yet, sadly, due to a horrible lack of content); others will choose differently, and as long as it fits them that's fine. That's why there are options.
