The question you're asking is extremely generalized, and the answers given are about as good and as complete as is possible.
Just to add a little. A lower RPM profile might be more radical, because there is something else limiting RPM, and it would therefore require as much spring pressure. In other words, if a given combination is RPM limited by something other than the cam profile, a more radical cam profile might be used to make more power at that lower RPM.
Clear as mud? It's hard to explain in a post on an Internet bulletin board, as there are time and space restrictions, and a proper dissertation/explanation would take up far too much of both. It is a very complex subject.
