This isn't necessarily true if you keep a tidy computer. If you have issues with your existing setup just don't migrate the settings folder which houses your library and preference settings.
The operating system deletes old system files it won't use again, and replaces ones it will. So technically theres no difference, migrating applications and data just moves them into the respective -/applications or -/documents etc. The exact same as if you re-download or copy items across.

This is true too, and I know it and ended up just doing an upgrade from Lion to Mountain Lion and not doing a clean install myself. The reason I always make the suggestion to do a clean install be it Mac or Windows is because in my 20+ years building/dealing/tech support I find that very few people actually know how to keep the OS on their computer "tidy". So giving them a clean install is generally needed and the safest route to go. It certainly doesnt hurt anything.
