It's silly to hate either of them. They're actually pretty nice people, from the very little I met of them at CEO. Hating a person for winning is silly. BUT, that doesn't mean that their playstyles can't be abominable. Smash is a spectator sport, and what they get flack for is just really really hard to spectate, because it's just dull to watch someone run away and time the other person out, or go for command grab suicide kills that have no real effective counter beyond playing in a campy fashion which is equally difficult to enjoy spectating.
