Given the choice of free P5 or free ds to work with I'd have a hard time passing up the major features in P5 that are lacking in ds.  I realize we can use both for free, but frequently time is more important than money and a secondary app that adds nothing substantial to the mix just costs more time.  I also like e-frontiers track record with software, which I can‘t say of daz.  A quarter million Shade users and a twenty year track record is significant to me, even if I'm not a Shade user.  If I have to bet on a horse then I'm betting on e-frontier and Poser 7.  P5 for free now can only help the eventual introduction of P7.
