Agrred and agreed (Male_M3dia/Moriador) - if you're needing extreme poses, you want Genesis/Genesis 2. Use the low poly mode for posing, and turn up the render mode poly count for your finished images. Also ditto Male_M3dia with regards to creature morphs, as you can actually have a wolfman who starts as a man and transforms into a wolf, using the same figure so it looks natural, rather than using a clunky frame to frame figure swap.

I was personally a bit disappointed with Genesis 1, but have found Genesis 2 quite liberating and now use it as my main figure in Poser Pro 2014 - getting the best of both worlds.
