Maybe I have only seen Samurai who don't know how to use Amanomurakumo properly, but I've never been amazed by it. I have, however, seen some pretty amazing things come from a Yoichinoyumi. Being able to solo Light, twice, with no enmity, is pretty cool. Also, all that stuff richardd said about Apocalypse doesn't sound so mediocre either. I've also seen Dark Knights use Apocalypse quite well, but most tend to make me cry that they have it and don't know how to use it.
