I occasionally use the poser native figures, if I need an out of the box background figure, but they have a disadvantage over the daz figures.
Poser native figures look like people.
I sometimes see posts by people like dphoadley and think "why does he still go on about using posette when the Daz figures are better?" But you know he's right! After Poser 4, when the bundled figures were given names, they became people. They already had human faces.
You would think that an advantage, but even as someone who doesn't create figures I can see that this makes it harder to create unique morphs and characters for them, where as with the Daz figures you are starting with a blank slate.

:-) if I'm redecorating the walls in my house, it's easier if they are plain and flat. I can paper them or paint them. If they are already papered or have some kind of textured finish on them, I have to strip all of that off and possibly use tons of filler before I can even think about starting on the finish.

It's good to have out of the box ready to use characters, I would imagine that most people want something that they can build upon, with plenty of partial morphs etc to help them. The face room seemed like a great idea when it was announced, but the vast majority of people cannot get a half decent head morph from it and although I own Poser 8, I don't even know if the new figures support it (and frankly couldn't care less).  I've seen head morphs done with software like Face Gen etc which are way better than ones done in the Face Room.
Several people have mention creating their own figures, that's great. I've used PhilC's quite a bit, I like them, but like the post Poser 4 figures, they are characters, they've already been "moulded". I know that other people have created figures in a similar vein to the Daz ones, but without the support they need from customers or merchants.
The bottom line is that if Poser wants to continue in the future without it's reliance on Daz figures, it is the company who owns and sells it (whoever that is this week) that needs to rethink the type of figures it produces and add better support for them. That should be their goal. After all we are buying  a character based 3d program from them, and it seems that although many people here have said they don't like the Daz figures ( I do for the most part, although I cannot get my head around Daz Studio therefore hate that!), they are the ones that are being used the most, so something has to be seriously wrong!

I hope that in Laurie's revolution, many great new figures get made,  :-)  but ultimately shouldn't that be what the people who are selling us this program should be doing!
