in my mind none of those guys is the best skier. I think the best skier is someone who goes out there everyday and skis for themselves and needs no gratification. But if your talking about most skilled jibber there are way to many disciplines and factors that you can rule out 1 best.
Josh Loubek really redefined the sport with his 360 screamin seamen but then a few yrs later there was josh loubek who came out with the flailing backflip but his friend Josh loubek stormed the competition scene with the no-grab-360. I dunno, sure JP and Jon and Pep and Boyd and Tanner and CR are all talented dudes, but no one is still pushing it like Loubek. Go watch his new seggy in Degenerates, fast forward to the hip and watch him pull the tizightest rocket grab ever performed on harts. Period.
My favorite pro is Jon but none is the best in everything.
Jon is the most technical.
Candide is the one that better it controls the big jumps.
Hall and Fujas the best jibbers.
Seth is the most radical and inimitable. He seems that he is crazy, and he is, but it controls the situations like nobody.
Seth. you cant argue. he has so much raw skiing talent in him. i didnt particularly like most of his seg in the front line (excelent skiing, not put together as well), but in high society, the first time i saw that i rewound it five times in awe. come on, the guy airs off a huge ass cornice, and lands in an avalanche. most people would die. seth skis out fine. below seth i would say aucliar, olsson, and mike d. (his style can get pretty whack, but you cant deny that he is an excellent skier.
In the world there are many pro-soccer players and everyone have their style but the best are Zidane, Ronaldo, Henry....
In the freeskiing it happens equally, there is many pros and all are good but there are some better that others.
I think that in the freeride seth is the best.
In the freestyle I believe that in the top be: Jon, Hall,Candide and Fujas but my favorite one is Jon.
