You cannot compare talents in a sport as diverse as ours at all. In reality most peoples responses to that question are gonna just be there favourite skiers.
I mean, the way Seth Mo shreds backcountry is completely different to pollard but Im never gonna claim who is better. Like wise, Seth Mo rapelling from the Aiguille Du Midi lift station in Cham to drop in is one of the raddest thing Ive seen. Yet, I will not see him smashin rails like Wallisch. And, I would hazard a guess that us older skiers would probably sight the likes of Auclair, Seth, and Candide as the 'best' skiers.
In terms of my favourite skiers;
