 If you liked Bleach |  ...then you might like Vagabond |
Both samurai sword tales but set for different audiences. Bleach features more colorful characters, more humor, and supernatural powers to add to the sword figting. Vagabond has a more adult storyline, richer character development, and much more detailed artwork. If you like Bleach but find it to be a little young for you, Vagabond is definitely where you should go. Note that Vagabond is a monthly manga, though. So the storyline may move slower than the weekly chapters for Bleach.
