Some of my favorites by checking the list are:
Death note - Psychological anime, exciting, Definitely worth watching
Tengen Toppa Guren Lagann - Great anime, a bit "childish" but still it's a great story though the whole "combining" thing get's really frustrating in the end.
Full Metal Panic - Hilarious first and second season, The third (The second raid) Wasn't as good due to the lack of humouristic events. Great anime for meccha fanboys
Nodame Cantabile - I'm still watching it right now but it's an incredible anime though it centers around classical music it might be hard to grip that it can also be entertaining while still having a good story.
Samurai Champloo - Definitely worth your time, Great fighting scenes and Mugen (One of the main characters) always makes me laugh. This anime has it all, Laugs, Fights, Drama and great characters with a sad background.
Code Geass - Enough said, though the second season imo isn't as good as the first
