The advantage is quite specific, but for older GPS units where you  
cannot change the background polygon colour,  
--generate-sea:multipolygon creates maps which display land as "Garmin  
yellow".  --generate-sea:polygons on the other hand creates a land  
polygon which you can specify in a TYP file, which is much nicer. :)
