World's strongest or world's luckiest? Which will you choose?

World's strongest or world's luckiest? If you have a choice between two, which will you choose? Most people will most probably directly answer with world's strongest but that's not the case for me who has never experienced luck even once and could be considered the world's most unfortunate man. Atleast that's what I have always thought until the day I suddenly found myself in another world with maxed out LUCK stats which is considered useless by most people but only I know the truth. But this situation is much more worse and grim that meets the eye. Almost a quarter population of Earth was suddenly got transported into this fallen world and EARTH is almost on the verge of destruction.
