I don't see a basis for your comment regarding Quintana. If anything, Froome's effort was more taxing due to the drag sprints. Another thing - despite variable conditions Armstrong and Pantani always seem to be at the top of these lists. I guess they had adverse conditions by contrast to the tailwind carrying Froome round France. Also a shame that Contador couldn't get near his 2009 time despite the favourable tail wind.
