The main problem I'm having is with shoes! My guess is that any Poser conforming shoes that were modeled around a posed foot (instead of the default V4 base) don't "line up" in Carrara.
The other issue is that certain hair props won't accept their MAT poses in Carrara. This is a known issue that's not really widespread.

I only use Poser (6) for the Walk Designer, and for easy posing (save them to use in Carrara animations). Also for creating conforming clothing meshes I've created in Hexagon. (fast/easy in poser to slap a skelly on a clothing mesh)

I end up taking my customized conformed clothes and using the tools in Carrara to fine tune them in the vertice modeler room (than using magnets in poser) much easier to do this in Carrara modeler.
Creating Carrara-Hair is easy in Carrara, tho tough going with animations for simulation/render-time, but all that calculating stuff always consumes much time (so much trial/error, lol).
