To me David Gandy is not versatile, he has a great career, has accomplished a lot for male models in terms of body image and the whole very masculine look versus the pale slim type of models that were before him but he does not do anything in high fashion, he is a great cover star and does lots of campaigns and I see him as a great brand ambassador but not fashion supermodel.
However Sean and Clément, in their own rights, have amazing fashion careers, do lots of runway shows, are very very appreciated in the industry, earn lots of money, do great equally on a commercial leve, do campaigns for tens of brands still manage to appeal to high fashion designers and magazines and photographers.
Lucky blue though... Hum yeah: apart from white hair and blue eyes I am sorry he does not have the makings of a male SUPERMODEL: the looks and social media don´t make one a male supermodel like Marcus S, Tyson B or Mark V indeed.
