From what I understand SAC is more in-line with the manga while the movies are kind of their own thing, but I've never read the Mangas so I can't say if that's true or not
Big EH to that.
The mangos are very different, same for pretty much all of Masamune Shirovs animu adaptions. As much GITS animu as there is you'd think the manga is some large piece of work, but actually there's not all that much of it, and fully half of it is the author crawling up his own ass with technobabble. The Arise series and later is just the author doing a cashgrab after spending all his hentai artbook money on hookers and blow, basically written for Netflix.
The one that stayed truest to the manga source is probably the Dominion Tank Police OVA series, which incidentally is fucking great.
Hueg glam metal hair, cyborg catgirls in leotards, lowbrow humour and action.
