So what would be your first pick for a Ghost in the Shell RPG? Full-body cyborgs, e-brains, tachikomas, offensive firewall, camouflage, terrorists, corporations, and government agencies.
I'm almost tempted to try a SLA Industries adaptation of GitS.
Without hesitation, Cyberpunk 2020. It gives you cyberware and netrunning out of the box. With the Maximum Metal book you get powered armors, and with the later Chromebooks (3 and 4, I think) you get total cyborg conversions.
If you wanted to stay absolutely true to the GITS style of netrunning, you'd have to add some house rules that allowed you to hack into people's cyberware. But otherwise, I'd say that the tech level and the gritty combat style are dead-on.
As second and third choices, I'd go with HERO (where I could just build all the cyberware, powered armor, and netrunning "powers" from scratch, and in detail) or else Fudge (where I could just skip all the rules fiddling, slap together some characters, and go). But CP2020 would give the best out-of-the box match, for me.

Probably Mekton Z. I'd handle brain-hacking with psi-powers rules and the full 'borgs would be built as 'Oids (SMT).
I'd want something that's both a little gear-heady and at the same time resolves action scenes quickly and with a minimum of fuss and MZ is well-suited on both counts. I think I'd build the Fuchikomas as roadstrikers with lots and lots of weight efficiency.
(Note: I've only seen the original movie and read the comics - I haven't seen the SAC series)

My wife ran a successful game using the Ex Machina rules. I can't remember all of the conversion rules. I know Dynamic powers were used to simulate the uber hackers and Tachikomas were bought servants.
I've actually been giving this a ton of thought recently.
M&M would probably be a good fit, but I don't know about the feel. It should have at least a LITTLE grit, and it should be possible to one-shot anyone.
Savage Worlds is a personal preference. Would let me run it without too much effort, but I'd have to come up with a good hacking minigame. Maybe adapt the mass-battle system? Hm...
Gonna say no to BESM, don't like the system.
Unisystem would be good in a pinch.
I think RandomAnime could handle it, but I'd need to amp the damage rules a mite.
