I do agree he's cooler. Never liked Clone Syaoran's over-polite demeanour very much. All Syaoran must be bratty and adorable, I say! And his CCSesque fighting techniques? I squeed to near death when I saw that.
I think he's sympathetic to Sakura-hime, but has a Sakura of his own in his dimension (least thats what I'm hoping). As for his goals, maybe after defeating FWR, he'd like to go home? Goodness how many years he spent in that fish-tank.
