It really depends on what you want to do. If you want to set up figures for rendering in other applications, use PP. The integration with other apps is non existent in P5. If you mainly use products as is, the PP may be better, because most products don't use the P5 specific things (yet) and may be optimized for P4. On the other hand, if you render manly in Poser and like to fiddle with things, P5 is much better IMHO. The material room alone is worth the update (materials options are very limited in PP). I spend most of my poser time playing in this room, it is so much fun and makes such of a difference in the render. I really like P5 hair because it enables me to create unique hairstyles in poser. It is true that the dynamics are bugy, but they are needed mainly for animations not for stills. I have not used the cloth room much, but from what I have seen from others, it seems to work well. Personally I found the user interface much improved from P4 (I don't own PP), but it is still basically crap. If they only had done a standard windows interface. Since I used P5, I would never get back to P4. I was able to realize pictures I could not in P4. stefan
