both of the animes have this "American" styl, some times same animation
the supernatural, some part of the story, characters
many similarities in the way of the characters are fighting, some times even the animation is similar
Full of bloody moments, perfect fights, excelent drama moments
Both of them are full of drama, both of the shows are about protecting something (Death note: the main character tries to protect justice and Code Geass: the main character tries to protect his sister) and the most crusial similarity in my opinion is that both of the shows are full of strategy and sometimes mind games. The ending of both shows is similar as well.
