As someone who took a couple design classes in college I can declare with authority that these are the best:
Vision Street Wear
HUF
Shorty's
H-Street
Blockhead
Foundation (both the clean Super Co. F and the messy moon logo)
Vans "Off the Wall"
Habitat
Gull Wing
Worst: Slime Balls, Limosine, Ace, Hosoi, GX1000, World Industries "Devil Boy", Blind "reaper"
