At the moment Pinot seems to show the most potential to be a GT contender after getting a top 10 in his first GT. But Quintana I would say is the better climber of the two, his performance at the Giro dell'Emilia and the Vuelta showed what a great climber he is, as well as a lot of potential. Would like to see Quintana get leadership in a GT though, instead of having to work for Valverde again.
