These are all the shows I watched:
The Melancholy of Haruhi Suzumiya, Great Teacher Onizuka, Ranma 1/2, Naruto, Ninja Nonsence, Welcome to the N.H.K., Full Metal Panic, Gurren Lagann, Neon Genesis Evangelion, Ichigo 100%, Fullmetal Alchemist, Love Hina, My-HiME, To-Love Ru, Bleach, and Death Note
I think that there all good but for a specific genre
comedy: Great Teacher Onizuka, Ninja Nonsence, and Welcome to the N.H.K.
love comedy: Ichigo 100%, love hina and to love-ru
action: naruto, fullmetal alchemest, bleach, Gurren Lagann
action comedy: Ranma 1/2 and full metal panic
magical girl/comedy: My HiME
comedy/sci-fi: The Melancholy of Haruhi Suzumiya
action/mecha: Neon Genesis Evangelion
death note has its own uniquie category
i havent finished watching a few of these shows so i may be wrong with some categories
i hope this helps
