My previous comment ("It is about the stylist and how they interpret the art.") is a generalisation and genaralisations don't explain the whole story.
I think another way of saying it is; 'it is not the camera that makes the photo great, it is the person taking the photo." A good camera can help only so much. The rest, the way it is composed is up to the camera operator. It's all in the way you use it, not just the brand of camera. The style is important but the stlylist and the way they use it is what really counts.
Again it is still a generalisation yet I hope that explains it a little better.
