well, from what i have seen thus far, i think sydney's face has more character, grit, life, whatever to it than V4's...i have V4 and i find her to be ok for the most part (crappy eyes and her teeth look like little pegs--sydney's teeth are great)...i haven't sprung for poser7 yet so i will have to wait to play with syd, but i think she's more my kinda gal..
