Why Do Google Maps’s City Labels Seem Much More “Readable” Than Those of Its Competitors?
For months, I’ve been trying to figure out why Google Maps’s city labels seem so much more readable than the labels on other mapping sites.
To me, Google’s labels seem to “pop” much more than the other sites' labels. Major cities also seem to stand out much more.  And whenever you’re quickly scanning the maps, the label you’re searching for seems to stand out just a little sooner on Google’s maps.
