I think the two mangas are quite similar. Both contain lots of bloody fights, more or less ecchi and the main characters look like bad guys at the first glance. And all the action is packed in very exciting storylines.
(if you try samurai deeper kyo, you should read the manga. the anime sucks. they changed that much that it doesn't has too much in common with the manga anymore)
