I've said this before and I'll say it again.
It doesn't really matter which character is more popular, better, has more clothes or is more morphable.
They are merely tools to an end..
If the proof is in  the pudding (the galleries). I don't see it.
I don't see a great leap in originality or artistic merit since V4 came along.
I would say, and I'm sure DP would agree with me, that you can get an outstanding render with Posette or Dork with P4 if you put in some effort.
Perhaps the "Make Art" button is what we really need more than anyhing else.
