Most accurate? Easy. Howard's maps (published in "The Coming of Conan" by Del Rey) are the most accurate.
Other than south of the Styx and east of the Vilayet, the ROK map (published in poster form with the GM's screen) probably is the next most, although it does have a few problems like all the maps do.
Dale Rippke's map is the only accurate map of Stygia and the Black Kingdoms I have seen. I prefer this map of
Hyrkania and Khitai (although Stygia and Black Kingdoms are wrong).
Another version with a REALLY wrong Black Kingdoms, but I like Hyrkania. One of these days I will try my own map with Dale Rippke's Stygia and Black Kingdoms added to some of those maps' elements.
