Poser 5/6 faceroom is a limited version of Facegen. I suspect the better flexibility of Facegen is due also to the fact that Facegen loads a "neutral" face where Poser 6 loads Jessi o James face. Poser 5 loaded a neutral face, similar to Facegen, and its faceroom was more flexible: would be good if in next SR - I hope there will be one! - CL will restore this possibility also in P6.
