Are we counting the U.K.? If so, my favorite is either Danny Brady or Lucas Puig. Honestly depends on the day you ask me. Brady is a footage machine and arguably the best fakie skater around. Lucas is a god-damn prodigy who has been releasing ridiculous parts since he was 14.
But, hm to Gustav, Tom Knox, JB, Nick Jensen, Flo Miritain, Hjalte, and Lucien. I expect Kyle Wilson and Charlie Birch to be up there soon. Huge fan of the old Cliche and Blueprint videos, and of current Atlantic Drift/Isle, Helas, and Palace edits. Arto and Penny are also up there all time but are defacto retired at this point.
Least favorite? No idea. I guess fuck that Jarne dude. I don't really dislike his skating(he has sick back 3's) but Blondie's schtick is a bit insufferable.
