Poser 1-4 have low poly options that look like FF characters when imported, poser 5 and 6 have higher poly figures great for foreground placement. Poser 7 has way too many bugs to even bother with, install is too big and it takes ages to load, and it lags bad.
so in answering...it depends where you want the figure fore or backround.
A useful tip: if import is clothed then remove anatomy that is not visible, including tongue, teeth etc, as that reduces the size considerably.
