Both involve a feudal environment giving off a pretty classic samurai film atmosphere.
Both also show a lot of graphical violence/gore.
Both Anime concentrate on samurai's and their bizarre adventures. both have very strong and dominant lead characters, who find them selfs following a certain pattern in the way to their goal
This two shows have very graphic gore animation, and lots of bloody and amazing sword fights
Shigurui is probably a bit more hard to follow, but both shows are very good and unique
