Koukaku Kidoutai: Stand Alone Complex, Darker than Black: Kuro no Keiyakusha Recommendations
Both share a similar style where a greater storyline is carried on by seemingly unrelated episodes (or episode pairs in the case of Darker than Black).
Show is episodic in nature for the most part and is a crime/drama as well.
They have a very similar feel to them. The story in DtB is a little darker than GitS, and the worlds are very different, but the seriousness and overall feel to them is very similar. If you liked one, you should give the other a try.
They both have an episodic "crime of the week" format combined with a long-term story arc. There are sometimes similar plots, and both explore the idea of people who are somehow different from ordinary humans (cyborgs in GITS, people with superpowers in DTB). Both are intelligent (moreso GITS), dark (moreso DTB), and mature and have kickass soundtracks by Yoko Kanno.
Both, Darker than BLACK and GiTS: Stand Alone Complex have similar plot build ups. While each episode seems mostly independent of the other on a deeper almost all episodes are related in some way. Also both revolve around a team protagonists (although admittedly both teams has its own protagonist)
These two animes revolve a protagonist with a strong support team in a political and action thriller featuring unique powers (although that's a given in most animes).
While Ghost in the Shell series revolves more around a central political plot, Darker than BLACK asks similar metaphysical questions underlying Ghost in the Shell.
Both are based around teams in secret organisations investigating and participating in missions.
Similar style of case by case operations, with undertones of something more serious going on.
Both groups have specialists in their teams based on resources and abilities that aren't available to general public, some of which must be kept secret.
International governments/organisations trying to manipulate and control information and access to resources.
Both series look over the implications on society after drastic changes to what being human means.
Earth and world are huge. Humans have to alive wisely among them.
Both solve social issues by antisocial forces. SAC is more grandeur.
These shows asking quastions about humanity and morality. Philosophical, and Psychologic.
Hei and Motoko Kusanagi are professional of crime eradication. They have unmatched ability from childhood.
Motoko is cyborg police officer. Hei is contractor, and known as The Black Reaper.
Also, They are my top-notch favorite characters. If you love adult characters, then they exist for you.
Both pacing is basically episodic. SAC have part of continuous story. DTB haven't it too much. Mostly divided into first part and latter part.
The animation and character development are decent. SAC
