To me the example photo has a much nicer background, out of focus highlites are rounder softer, and colors are muted rather than cat eye, the face has more depth of field. This caused one objectionable highlite on the model's left side, the others look better. The face looks more evenly illuminated, likely due to the greater depth of field. When you compare the two images there are a ton of tiny things that render differently, but the main effect is that the model seems to pop out with more separation from the background, and the background is smoother and muted.
If I were doing 95% portraits, I'd get the DS based on that photo, but we need to see more first.
