The limitations of DS' dynamic cloth (requiring custom prepped meshes) do seem at first glance to be a disadvantage. I'm not sure how true that is though if indeed there is a lack of clothing that really is designed to work well with Poser's dynamics. The advantage of the DS  stratege from what little I've seen is that with the proper clothing it looks to be perhaps an easier - closer to one click solution. Poser's advantage is that with skill, you can convert just about anything to dynamic. DS offers an easy version and for more money if you want a more advanced version though still not as versatile as Poser. Which is the "average" user going to prefer - ease albeit with purchasing more content in what has been dubbed a content driven market, or greater power with greater complexity? I'd bet on Daz.

Poser is IMO, admirable for putting more power in user's hands but be neglecting the need to make that power accessible to less accomplished/patient/dedicated/insert adjective users, it risks ending up in a place where the complexity puts off the low end and the high end users prefer apps like C4D. That's fine for the segment that wants a more powerful application at a lower price point or likes having one app do it all but I have some doubt whether in the long run that's the best strategy for growth. The potential killer for Daz is the mounting cost of adding features, but given that people can pick and choose and they are already used to dropping large amounts of cash there on a regular schedule, I don't know.
