you cant even really go by who has the most footage in terms of minutes either because i would say Marc Johnson and Jamie Thomas probably have a similar amount of clips but Jamie's hyper fast cuts make his parts go by so much faster than ty evans slow mo edits. also someone might just have a fuck ton of lines where its just pushing for time like jason dill.
i think you sort of have to put your own perspective on this question and then it kinda comes down to like, who has produced the most quality content over the longest period of time. You can almost directly translate it to how long someone's career lasts for. so i think the list I put is still relevant.
Marc Johnson
Pat Duffy
Jeremy Wray
Kris Markovich
Daewon Song
Rodney Mullen
AVE
Penny
Koston
McCrank
Also Reynolds, Duffel, Cole, Suciu, Ishod as others said
Jamie Thomas
Ellington

Gonz
Brian Anderson
Leo Romero
Joslin
Heath
Tyler Bledsoe
Grant Taylor
Mike Carroll

Louie Lopez
Ryan Decenzo
Paul Rodriguez
Wade Desarmo
Spencer Hamilton
TJ Rogers
BDK
Biebel

i dont think there is anyone on this list who hasnt had a pro shoe besides BDK and TJ, most of them having multiple pro shoes.
