Difference is that in One Piece they kill off important characters that are "good guys", while in FT they don't (Igneel doesn't count imo). And in One Piece there is just way more death in general, like people with no significance to the plot (random Marines, pirates, citizens) die all the time, while in FT not so much. FT is for me, even with the fanservice and the blood and gore, a much more "mild" series in comparison to One Piece.
