 If you liked Vagabond |  ...then you might like Shigurui |
There are many instances in these series that are quite similar such as characters, especially samurai, who aspire to be stronger in terms of their skills in swordsmanship, or same desires of individuals who want to conquer their obstacles (i.e. enemies or hardships). Also, numerous historical events and people had been mentioned, although in different circumstances. Both art are marvelously realistic, but Shigurui takes the gore level higher than Vagabond.
Both have a mature and dark storyline wich follows a couple of strong induviduals in the Era of the Samurais. They are both drawn in a very realistic style wich furthers the story and the setting.

So far Shigurui is the closest to Vagabond in terms of theme/genre, martial Arts, samurai-life and composition (it can be heavy on dialog at times, however it doesn't fail to replicate Vagabond's beautifully aesthetic panels with little-to-no text). The gore in the manga can be a tad over the top with the art REALLY demonstrating it with details.
