The geographer's catch-all answer to practically any question is, "It depends upon the scale"--and therefore, the extent of the area being analyzed. Is this a city block? A city? A county? A state?. This principle applies forcefully to the selection of elevation ranges in US maps. The elevation color scheme that shows the Rocky Mountain region to advantage isn't much good for the Appalachians, and visa-versa. 

The Raven US elevation maps represent the best compromise we were able to come up with for all 48 states, but we are developing a set of maps to do better at the regional scale.

Examples:  Inter-mountain; Mississippi Valley; Appalachian/Eastern seaboard.
