That's the thing... we're both speaking in partial ignorance, since I haven't gotten around to getting a new copy of Poser, so I'm going off of what I've read here and on featuresets/spec sheets. (seriously - I still have 7, and I've not bothered to re-install it yet, preferring to just jump into the latest when I get the budget (and a way bigger hard disk) for it.)

As far as feature comparisons? It gets murky in places (Fitting Room versus Auto-Fit, not sure what parallel Poser has to Smoothing/Collision-Detection, etc.) but otherwise, they're about even, each in their own way. DS does have more tendrils and often outright plugins out to other applications and render engines (e.g. Octane, etc), but that's mostly workflow and convenience stuff since from the looks of it everybody can import/export FBX.

The more I look into iClone, the more I see it lacking (though in some aspects, having a Maya-ready rigged Poser/DAZ figure with little-to-no-effort would be hella cool, should I ever get the urge to use a top-end render engine... though I could use Octane w/ DS right now, if I ever felt like coughing up $500 or so for the stupid plugin from OTOY. Anyrate, I'm rambling off-topic here... :) )
