It might be skirting the edges of what is considered cyberpunk since it has Mecha elements but Patlabor is a fantastic manga/series that should have been included in this list [1]
Patlabor movie 2 was directed by the same director as the original 1995 GiTS animation movie. Both patlabor 1 / 2 have similar themes to GiTS, and are heavily cyber punk in themes and esthetics.
1. Patlabor The Early Days (88-89, 7 OVA) -> Patlabor (89, Movie) -> Patlabor 2 (93, movie)
2. Patlabor The TV Series (89-90, 47 eps) -> Patlabor The New Files (90-92, 16 eps) -> Patlabor EZY (26-27, 3 movies)
The new one (EZY) is amazing if you haven't seen it.
