I tried rendering two girls, one from Mousso (MacKenzie, an older G8F model) and one from Anagord (Leila HD, a newer G8F model) in the same exact conditions (same lights, same clothes, same skin effects, and a couple of dials; one to enhance the pose and one to add a tiny bit of detail, both at the same strength).
Also, they had to use assets coming from the original model (skin, make-up, etc, except eyes, which they are using the same 3rd party color), and NO postwork.
Here are the results:
MacKenzie (Mousso)

Leila HD (Anagord)
