In some metropolitan areas that cross two (or more) states, there is often one side of the state line that is considered more prestigous, with more affluent residents, better schools, better planning, and so on.
Of the metro areas I know of that cross provincial or state lines, the better side is considered:
Chicago: Illinois (vs Indiana / Da Region)
St. Louis: Missouri (vs Illinois / East Metro)
Washington, DC: Virginia (vs Maryland and the District proper)
Kansas City is strange. Kansas City, Missouri is considered much nicer than Kansas City, Kansas, but the Kansas side suburbs (Overland Park, Prairie Village, Leawood, Olathe, Lenexa, etc) are considered much nicer than the Missouri side suburbs (Independence, Liberty, Gladstone, Raytown, Blue Springs, etc).
IMHO, of course.
What about other bistate metro areas, such as Cincinnati (Ohio / Kentucky), Ottawa (Ontario / Quebec), Jacksonville (Florida / Georgia), Omaha (Nebraska / Iowa), Portland (Oregon / Washington), or the Quad Cities (Illinois / Iowa)?
