I bought Poser5 the day after I downloaded DAZ|Studio (2005-01-05), and used them concurrently for about six months, then bought Poser6. As far as I'm concerned, Poser is a special-purpose tool who's only really useful feature is dynamic cloth. The dynamic hair looks like dog poop, so you can keep it. Poser is intolerably slow (I have a 3.4GHz P4HT w/2GB RAM and an nVidia Quadro FX 3-something that cost me US$1,300.00), so I'll stick to DAZ|Studio unless I'm really bored and want to spend ten minutes trying to rotate my viewport ten degrees. And speaking of rotating my viewport, what kind of drugs were the Poser developers on when they wrote the camera manipulation code!?! I've done a lot of photography as well, so don't hand me that crap from the manual about 'it's more like how a photographer would move his camera'. DAZ|Studio: point the camera at the object and it becomes the focal point of manipulation. Sure you can do that in Poser, but it's like pulling teeth to get it to work right. And Poser's magnets make me insane, the D-Form plugin for DAZ|Studio works much better, more predictably and with less waiting around. The only real feature DAZ|Studio is missing at this point, that requires that virtually every render go through at least some post-work, is that the 3Delight renderer can't really do smooth polygons the way FireFly can.
