I started out with Poser - and still use v. 6 for a few things, particularly importing conent from other formats - but DS has been my primary app for about three or four years, now. I actually paid for the 64-bit version, mainly because of the morph follower (not perfect, but works well enough in most cases).

DAZ is definitely faster and easier to use...I have also found that about 98% of all Poser items work in DAZ, but I still find myself using the Poser runtime for virtually everything related to libraries...have never been able to figure out the DAZ runtime structure. (In fact, while I've had few problems using Poser content, I've NEVER been able to use DAZ freebies...)

The other drawback about DAZ is if you aren't careful about keeping the DAZ Runtime folder absolutely intact, you won't be able to open your old scene files (this happened to me when I went from v.2 to v.3, destroying months of work...) This does not seem to be an issue in Poser.

DAZ is also less flexible when it comes to importing props in different formats. It doesn't support texture tiling, which means some Poser props look like crap when loaded into DAZ.

One thing that I'm pissed off at DAZ for is the fact that their dymanic clothing is NOT supported in the paid 64-bit version (the free 32-bit version DOES support its dymamic cloth, however).

Another frustrating thing about DAZ, especially when it comes to big scene files, is that it takes them a  L O N G time to open and save - and if you use DAZ for an extended period, it starts taking longer and longer to select body parts - and it eats up your RAM until you quit and restart the application. (Memory leak?)

One other thing....if you create a character with specific morphs and save it to a Poser library with clothes, don't expect it to work when you open it in DAZ from a Poser library.
