Both shows focus on a protagonist who is cool-headed investigator working as part of an organization that tries to maintain some peace and order. Both are keen observers of human nature and have family members they care for, and both (by chance) enjoy smoking tobacco. It's mostly the vibe though as both have a similar smooth-jazz thing going on. They both are relatively mature and realistic in their depictions of people and their motivations and I think people who enjoyed one would enjoy the other, although ACCA is more about intrigue while Onihei has a little more of an action focus.
