Cowboy Bebop is up there for me. I will allways love my Robotech, older series are just that older, but still good, it ages pretty well, the newer seires are very well done graphic wise. Samurai Champloo was good too, I enjoyed Trigun, I enjoyed Full Metal Alchemst Mostly becuse its so fucked up half the time. I would recomend Outlaw Star, and if you dont mind older graphics robotech.
