enigmafox - One thing you are saying i don't understand: you are talking about a modeler "Poser friendly " to make content for Poser such as props and clothes. But to do so, you only need a program that can export in obj format into Poser, and the rigging is done in Poser. I think all the modelling apps export in obj format, so i guess all the modelling apps are "Poser friendly" in the way you are talking about.
There is no native modeler for Poser, as it's IN Poser you transform a simple obj in a pz2.

You have to consider the prices too, as an app like Modo is FAR more expensive than Hex (or Blender of course). If it's not an issue, try your way around them.
As an Hex user, i must say you can do all you want for Poser content with it without any problem. Even morphs, you only need UVMapper (which is free) if you want to import an already grouped obj into Hex to make a morph. You also have tools for 3D paintings and displacement sculpting (even i didn't use that feature).
