(translated from french)
Both take place in post apacolyptic setting, includes adavanced robots/AI and has a good and action packed story
I recommend it because it's in the same cyberpunk and psychological sphere.
both are similar in action and having strong female lead characters.
Both of these anime have similar settings, and feature a smart female detective as the leading protagonist. They have similar themes about the problems prevalent in a society which relies too heavily on technology. After all, there are always bugs or loopholes that can be taken advantage of. The art and sound in both are brilliant as well. Finally, the most notable similarity are the heavy philosophical themes in both shows. GitS and PP both analyze human society, and also try to define humanity itself.
If you like sci-fi thrillers that involve complex plots and dilemmas for an hypotetic future civilization, with philosophyc touches, this is what you are looking for. Both are about police units and their struggles to resolve complex crimes. Both have a great ambientation with strong cyberpunk inspiration. Both soundtracks are great. Both have a great plot and characters.
Both introductions to carefully crafted universes, that seduce you through their effervescent world building and master class study of the hypothetically futuristic human condition, and never quite let go.
A cyberpunk relation regarding both shows is established, as well as a futuristic setting. The formulation of thought apropos human thought; what it is to be human Vs the 'society', how the society would view you for being any different from anyone else. One may recommend SAC (Ghost in the shell), but the movie is a much better relation.
They both take place in a similar futuristic setting and ask questions about society.
Psychology based on robot and ia through sf
Both deal with a futuristic setting and deal with the philosophy of humanity, morality and choices.
