When you ask a person about his opinion the background is all important. For example I would be interested in Ingemar Bergmans opinions that goes without saying.. But there are two groups of people which opinions I am NOT interested in, like
A) Long time Poser only users who never will switch to Daz Studio, and
B) Long time Daz  only users who never will switch to Poser.

Category A & B, please don't bother.

People who are thinking on switching on the other hand, why and wherefore that is interesting. Hearing the reasons. Daz's free offer has certainly changed the playing field. In addition.

1. You can now make cloth just as easy as in Poser, or easier,
2. The new documentation is far better than anything Poser related.
3. They have an SDK (!)
4. A plug in for Octane is just around the corner. (I will give up Vray for Octane any day!)
5. Daz has a successful business model unlike some.

Actually there is only one reason left to use Poser IMO, the cloth room. But how long will that last? The technology in the cloth room is old and outdated.

Just my personal observations.
