My Tamagotchi owns your Tamagotchi (it'd be sad if you started seeing bumper stickers like that... or "My Tamagotchi is an honor student at Tama Middle School" or something... hehe only dorks would do that... ^_^ ). Anyways, I think the Japan version would be best, because everything from Japan is better, but from the picture I've seen of the U.S. version, I think the American ones look nicer. All Tamagotchis are special in their own way... ^_^
