Style vs story discrepancy

[Elvis]

Name some manga that have a big discrepancy between their graphic style and their story. I mean, manga in which the style is really good, but the story sucks, or the other way around (the story is awesome, but the style is not very good).

all the popular manga's art is never good.
look at one piece, the art isn't awesome but then again it's got stuff.
