If you loved it
I don't know any shows like it, but the only thing that felt remotely close to it was Darker Than Black. Give it a shot
P.S.
I think the latter is better
I'd say I'd rank them the same. I like them a whole lot better than anything Ghost In The Shell since the first movie.
"Need" is just a fiction. As is "should", "must", "value" and "importance".
