(correct me if I'm worong please) Fox was the only company that had 32mm+ stanchions for all their forks, but now a lot of competitors are going up to 32mm too. I've tried a Fox forx and was surprised that it wasn't smooth as others commented. My RS Duke was smoother than that 06 Float I tested.
I would love to own a Fox, but their cheapest fork is almost the same price as some high end fork from Marz/Manitou/RS.
