Koukaku Kidoutai: Stand Alone Complex, Un-Go Recommendations
The art isn't very similar but the settings are extremely similar. Both take place in a cyberpunk future that is somewhat dystopian or otherwise given over to a government that has a lot of control over its citizens and the information they are given. Both delve a bit into technologies like androids and information technology and censorship. They are also both crime/detective dramas, GitS more so crime and Un-Go more so detective work. There's are nebulous references to a big war prior to the happenings of the story and and both main characters origins are a bit mysterious.
There are some differences. GitS has a bit
more action, while Un-Go has a supernatural aspect not found in Ghost In The Shell, and in GitS the characters work for an independent government agency while in Un-Go the main detective character works more or less alone against the government. GitS features more of a 'team' while Un-Go is closer to a duo that expands into a trio a little later on. And again there's the art style.
Still, both are good anime so check them out. If you like Cyberpunk, both of these are great choices.
Let me be straightforward and to the point for this one. Both shows may have extremely contrasting viewpoints and plots; with GITS having the viewpoint of the police Public Security of Section 9, whereas UN-GO features two partners who try to resolve the mystery and conspiracy from within their country. (Though primarily forced by Inga, a supernatural character, so this aspect which is extremely similar to Neuro.)
However, these titles share two words: Truth and Justice. Both shows heavily emphasise on justice as not just a belief, nor just a rationale; but as a fact, a human desire. Despite being heavily undermined by the top
brasses, Section 9 in GITS never waver despite all the adversities they faced when their corrupted government tries to cover up the issue, endangering their lives in the name of truth and justice. In the case of UN-GO, Shinjuurou is known as the "Defeated Detective", but the "defeated" is but a farce; a facade placed on him and Inga as conspiracy theorists, despite being the true detectives. Heavily observed and subjugated by the higher-ups such as the corrupted Kaishou family and the National Police Agency, the pair attempts to solve the mystery behind their government, while risking themselves behind the actions of the corrupted government.
Both shows also involve heavy conspiracies, which are all apparently, true. The stealth, lies, and distractions from within both shows are what bring forth the beauty of this titles, and it is an aspect that one "cannot dislike.
Both shows also depict a dystopian society in the aftermath of a devastating war, (with GITS being WWIII and WWIV while UN-GO being the War on Terror) and the impacts towards society from within. People are left for dead despite lying on the floor, bleeding; [when Togusa got shot in Season 1] (depicting the fear and apprehension of the society into heavily desiring a peaceful life and thus minding their own backs, albeit a false peace) the society relies on a higher, corrupted power for control, due to fear of another war, and live in fear; (as observed in the glorification of the Kaishou family) and many more instance I've yet to name.
Watch both shows. Do not be indecisive or skeptical anymore. Don't live in regret--not watching these titles.
