Soukihei MD Geist, Kakugo no Susume Recommendations
Both titles are set in a post-apocalyptic setting and are very similar in tone and content. They are very action-packed filled with nudity, violence and gore. In both anime, the protagonist has access to an armor that allows them to kill anyone that stands in their way. None of them are good as far as plot goes. However they can be both very entertaining to watch. If you like one, you probably will like the other as well.
