looking for good sci-fi anime, what do you recommend?

I loved:

Fullmetal Alchemist, This Ugly Yet Beautiful World, Speed Grapher

OK with: Cowboy Bebop & Samurai Champloo (wanted a better plot)

And tons of animes that I rent I think are totally lame. Any ideas for a good series? I liked the depth of the characters in Fullmetal and Speed Grapher.
