Who do you think has the best backstory in One Piece? (I mean history, like what did they face to get to where they are now.)

Personally, I think for me it'd have to be Sanji first, and then Nami second.

Sanji went about 70 days or more (I think) without food, or proper hygiene.

Nami had to pay Arlong a large sum of money to pay for her village.
