In my experience the big divide between Daz users and Poser users is the interface. I've used Poser since Poser 2 and I'm used to it. 3DSMax and Maya have a similar feel. DazStudio's interface is totally different and it takes me a LONG time to set up stuff in DazStudio versus Poser.
That was before DazStudio v10, now it's not usable at all, I can't download stuff from Daz3D into DazStudio, the library paths are hidden from you. It is PAINFUL for me to try to use it. A scene could take me 40 to 52 hours to set up in DazStudio to render it takes me 24 minutes in Poser.
