OK what I'm seeing is this:

You're looking for a massive amount of personal opinion on something that everyone is going to feel differently about.

I, personally, would prefer to see a nicely composed, well thought-out and/or high-quality detailed in postwork Poser render than some crap, quickie, slapped together image rendered in what would be considered a 'better' program.

Its about art people... Not how much money you spent to make it. I love Thomas Kinkade, I think his work is incredible. I don't care if he got his paint and brushes online from some exotic over-seas exclusive dealer or if he bought them for $2.99 at Hobby Lobby. Its about the final product and if it looks good.

So yes, I would rather see a beautiful render come out of Poser then something very poorly done from something 'better'
