in addition to the other distinctions already pointed out and speaking from a chicago persepctive, where almost all of our new residential/hotel highrises are RC and almost all of our new commercial offcie highrises are steel frame/concrete core, it is said that steel framing is prefered in office buildings because it is more economical than RC in super long clear span applications, which is a BIG selling point for commerical office space. conversely, super long clear spans are not particularly advantageous in residential/hotel programs as room sizes are typically far smaller and are thus more easily worked into and around a tighter column grid, which is said to economically favor RC.
