In that case, actually there are advantages.

Poser 9 has a couple of bugs in the addons framework that cause issues with parenting/unparenting of objects when using plugins. Poser 10 with the SR3 fixes that issue.

Poser 10 also introduced subdivision via OpenSubdiv, Reality 3.1 supports it.

Cheers.
