It's what you are accustomed to: Coke...Prius (because I'm a geek who likes to watch the graphical feedback)....Starbuck's Iced (straight up)....Fake Butter on my Popcorn.

I use both...plus C4D/Vue for a lot of my renders. I like Daz for the aniMate series....I can make a finely tweaked animation and export it to Poser Pro.

I have also been experimenting with Daz and Collada(whatever) and find it works well in C4D 11/11.5. But  I use a lot of dynamic cloth and I find the Dynamic cloth in Daz not ready for prime time. Also Daz does not interface with Vue...Poser Pro does...this is also important, for me.

Poser 8 is a vast improvement over the other Posers, but I'll have to wait until Poser Pro 2010 to get the export advantages. There have also been big improvements in Poser animation with "dependent" linkage of movements. The arm bends and the bicep muscle can be dependently morphed on the amount of bend. You can make the direction of the twist of the neck dependent on the direction of the eye movement (or vice versa)......to me this is big, and could, eventually put Poser into getting the respect it deserves.

I talked to some of the developers at Siggraph 2009, and I can tell you that SM is quite aware of Poser's potential and they are a hard-working and enthusiastic bunch. I'm amazed at how much they get done and how little they sell this amazing program for. I just bought C4D 11.5 Bundle for nearly $4000....yes, it's expensive....yes, it's worth it...I feel Poser is more than a bargain. I also own the Daz Pro...I just haven't used it for "finished" pieces because I haven't found the lighting I like ..... The downside to Poser, which I expressed to the Poser designers is the extremely awkward lighting setups (hate it)...that's whay I buy so many light sets.
