Sure other people can give their opinions.
But aside from myself and IsaoShi, who so far actually gave any relevant opinions to the OP's question?
The question of course was "Poser pro vs. Poser 8, pros and cons?"

I really don't think something like "The results from Poser 8 are just so much better." is exactly a comparison, and if it's a "pro" it's seriously lacking in informative elaboration.
