V5 is only easier to use if you're a DS user and have had issues using V4 (some of the DS artists I follow are still using V4).  IMHO, it doesn't make sense to say that it's good for DAZ- with multiple teams of developers, more than a decade of experience, and a whole lot of income- not to make a Poser version of their figure using the converter they made themselves and thereby avoid maintaining two versions of a single figure, but users, who do this in their spare time, use their spare money, and don't know as much, should maintain two different systems for everything.   Just like DAZ would have to hold back full exploration of DS features to give Poser features time, Poser and DS users would have to hold back full exploration of their chosen app just to duplicate the functionality they already have.   And where DAZ would get paid thousands for supporting Poser, DS and Poser users will by and large make zilch for learning a new lighting system, new material system, new fitting system... 

It's cool if your usage is basic enough in either app to translate,  or you're brilliant enough in 3d apps in general to be able to get anything to do what you want.  Or if you just like learning new software.  More power to you.  But I think acting like it's just stupid or dogmatic for individuals to not want to waste time relearning the basics for a purely horizontal change in software but not come down on DAZ for refusing to use its own exporter (for good reason- maintaining multiple versions of project rarely goes well and takes tons of effort) is just picking on the little guy.

I haven't had too many fitting problems since Wardrobe Wizard came out.  Now I make my own dynamic clothes, and almost never have any fitting problems.   Then there's the morph brush, and other tools.  Compared to what I've seen of AutoFit distortion, and how well some conforming clothes have converted to dynamic for me, I don't see AutoFit as having much appeal.  I haven't had an issue with V4's resolution, and if all I want to do is make scaled V4 characters, I can do that in PP 2012 without buying a whole bunch of duplicate morphs.
