Mercator is the most accessible paper map. The Authagraph is the most accurate due to low distortion. It’s not listed in the comic, and can be confusing to use as a learning tool.
The real question is why are you so committed to flat maps in the digital age? I don’t even understand why Google Maps doesn’t correct to a spheroid when zoomed out like Apple Maps, requiring users to download Google Earth for accurate representation of land mass size comparison.
