The thing that sets the CGSociety images and the Poser images apart isn't just the professionalism. I've seen some pretty damn professional looking Poser stuff.
The thing that sets it apart is the fact that none of those images sport the same outfit / texture in a variety of poses, from different people.

And God help you when you happen to say "Guy stuff". You practically get rocks thrown at you by a lot of people.
Reminds me of this:

Stop! Stop, will you?! Stop that! Stop it! Now, look! No one is to stone anyone until I blow this whistle! Do you understand?! Even, and I want to make this absolutely clear, even if they do say 'Jehovah'.
THUNK.
Alas... That M4 thread over yonder kinda... died. Instead we're "teased" with V4.2 Elite.
