Regarding SIC maps, they feel useless right now because they don't work half the time, and when they do the maps are really hard to read and don't really work as a map that much.
They're much inferior to Grid maps or even just learning the layout of the city yourself.

cmap is a rather a stripped down version of a coded navigation system that is used with other game mechanics. Compared to the advanced versions it is fairly basic, but it does give a taste to players as far as how other, more involved systems will work.
It's probably better to think of it as a navigational tool than a street map.
