It's the top one! The clue is in the meridians, on the bottom one they're curved to perpetuate the lie that the earth is a ball! Mr mercator drew his maps properly with straight lines as the goddess intended.
@HannibalAteMeOut yes because if the lines are straight there's no pretending the world is round, ist the curves that create the illusion. I'm fairly certain you can also have no lines just like in reality.
