Lightwave, despite its many UI quirks, is very easy to learn and numerous aspects of its workflow show they have done their best to listen to their users, but designing UI wasn't their forte.

Lightwave has reasonable support for Daz/Poser contents through FBX, Poser Fusion, and this plugin.

Bringing Daz/Poser contents into Blender is still somewhat of a challenge, but I will definitely use Blender the minute this issue is resolved.
