Anime Girl comes with Superfly materials. There are Superfly renders in the promo pics.

Just judging from the galleries, a lot of Poser users do toon or comic type renders, or do a lot of postwork. Some actually composite SF and FF renders, because they like elements of both.

Personally, I prefer the look of Firefly. It looks sharper to me (and if I want it less sharp, there's Photoshop). I'm not aiming for photorealism; I think even Firefly is well into the uncanny valley, or can be. I don't care for the "gaming" look that a lot of 3D art has, either, with super shiny metals and such. And I can never get hair to look decent in SF. It either ends up with a really painted look, which doesn't match the realism of eyes, skin, etc. or it looks really plasticky. Maybe I just haven't found the right shaders yet.
