Both maps below show Comoros highlighted. At 12° Mercator inflates Comoros by only about 4%, so the two maps largely agree on it. Watch what the old map does to Madagascar beside it. That contrast is why the new world map matters.
At 12°, Comoros sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
