Noooo... One Piece graphics are fine, it suits it... too good graphics would made it bad too
They did make a bit changes in the graphics a while ago
Card Captors, Sailor Moon, Chobits & Love Hina
The battles are good but it happens only once every 100 episodes?
Oh wait sorry I mean twice every 100 episodes
Pokemon, Digimon, Yugioh, Dragon Ball, Inuyasha.
Those bring back some good memories.
One Piece > all.
My top 4 shounen anime would be
One Piece
Gintama
FMA: Brotherhood
Major
