And on your second chapter.

Yeas agreed, the Load - dress - render guys, will be better off with the free DS and buying content as required.

IMHO, Poser is the better app, but it requires time and effort of the end user to learn all the tips and tricks..

ROFL, like there's not a ton of load, pose, render folks using Poser. No less time is required for DS users to learn all the tips and tricks - at least there wasn't for DS3.  I can't imagine much changed with DS4, particularly since there is still no user manual.

None of these apps are "easy" and Blender certainly isn't required to use Poser.  No other app is required.  The fact that you like to combine the two is your personal preference, nothing more.
