I am currently a user of both PoserPro 2012 and Daz Studio 4.5 on my mac running Mountain lion; I've used Poser since Poser 2 and Daz Studio since Daz Studio 2.  I can't say that I have the insight that the various vendors do but I have made my peace with both companies at this time.  I love the look of Poser renders and have always been a fan of the quirkiness  of Kai Krauss interfaces (It makes me smile when people here mention how they can't get used to the interface of Daz Studio which is closer to other 3D programs and prefer the idiosyncratic Kai Krause interface of Poser).  If I were to offer a critique, I would ask if it would have killed SmithMicro to support a mac supported tkinter for scripts and ask Daz3d to make an effort to make some of the genesis clothing less "rubbery" looking but on the whole, I am happy with both efforts.  I buy from pretty much all of the stores.  I am especially pleased that I can open most of my legacy Poser stuff in Daz Studio, that often vendors make stuff for both characters so I can render in both programs, and find that when one tweets shading rate, they both render at about the same speed with similar quality.  It is also nice that there will be parity in Reality (one can use LuxRender with Reality for both platforms but, boy, what an enhancement in work flow speed).  I remember enough of the launches of the various sites (as well as being aware of the economies of scale now and the legacy stuff that clogs the pipes) to look forward to Daz3d's site being 100%.  Bryce, the big issue is that it is old enough that finding people to work on its innards is a problem. I don't like this strife; I think it is important for both communities to remember that we are all rendering together and need to direct this religious zeal outward rather than inward.
