Noir is really good, it has a very realistic feel to it plus a wonderful setting and Ambiance. You might also like Golgo 13, and Kite (though I found Kite really depressing). Azumanga Diaoh is a pretty good one, it's not really scifi, just a story about normal schoolgirls growing up together. It is a bit more on the humorous side though, so if you prefer the stuff like Perfect Blue then I'd stick to something like Golgo 13.
