I agree that the test was far from perfect. Camera was in manual.
I do think that the lighting is close enough to further the discussion.
One variable we don't know about is how much manipulation was done to the example used in the op, I didn't take that shot. Hard paper, burn & dodge, PS, who knows?
My fav as just a straight portrait is actually the classic metering shot. This is just a mood/personal pref thing though.
I do think the one done @ -2 from classic is underexposed too.
