Both, while being borderline Hentai titles, have an actual well-written story behind them rather than a flimsy pretense prose for the sex scenes. Both are also about a male lead character who finds himself controlled through blackmail by the female protagonist, but their relationship, while adversarial at first, grows and changes as the story goes on. I also think both have above average art for this type of genre.
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.
