I must confess that I was a hard sell, I'd had serious issues with preceding versions of Daz Studio--but with DS 3 Advanced I felt things started to get better--conforming clothes simply worked better in it than they did in Poser for some reason, but I still used Poser primarily.  When 4 came out I was skeptical, I held off and then watched the promo videos.  I said to myself do I want to invest in a line of figures I can't use in Poser--but the ease of use and versatily drove me to try and I really like it now.  So I'm not trying to convince anyone of anything, I'm just saying I like Genesis, but am also eagerly awaiting more human figures that have content support and are good to look at so that I will have new stuff to use in Poser also.  I don't really think that Daz Studio will kill Poser--I just think there is a fork in the road here and Poser and Daz Studio will go on to develop separate and different, uncompatible ways of doing things.  This shouldn't be looked at as bad thing though, I think it just give a person more creative options.
