edgar,of the ones u listed that i watched, i say:
death note is awesome!
dragonball z- is "ok". it was a trendsetter and mainstream and has its good points, but a bit too long for me.
ninja scroll- just "ok". kinda weird at points
cowboy bebop- i know it is pretty popular, but i hated it
champloo- i liked it a lot
Yes Death note is the way to go Not even a quastion there
easily the best serious drama anime ever made
by far
Dragon ball i loved but as usual long and omercial
If you like that thats why i recomend samurai 7 and fullmetal brotherhood
both comercial and good
beboop i never survived, I guess i am not a fan
just like i dont like One Piece
Other that i LOVED very recent ones
The legend of the legendary heroes is an unfinished AWESOME business
really Its the best next thing since Code Gueass
Grandhild of nurariyo is awesome too one season of greatness the best yokai anime i ever saw, i admitt i didnt saw a lot of yokai anime
Theres another one
Sengokou Basara Very good anime with lots of fight and action
I am starting to love Bleach another loooooong one
