Full Metal Alchemist
Neon Genesis
Outlaw Star
Mobile Suit Gundam: The 08th MS Team <--- The only Gundam that is worth watching
Rurouni Kenshin
Something about these five... are good. I'm not the biggest fan of Anime but these ones are certainly good. I really liked the story arcs in Full Metal Alchemis, Neon Genesis, Outlaw Star, and The Gundam mini-series. Rurouni Kenshin is just too epic.
Your poll, as stated before, has only one true anime. Teen Titans and Avatar both have Japanese influence but are not anime.
