I believe that Corn's generally get a little longer in length than the kings do. Corn's there are so many different morphs to choose from, but you maybe a little more limited in your chose with a king. Here in Charlotte kings and Corn's are priced about the same, depending on the morph. They are both docile snakes, although I think that the kings are a little more secretive snakes than the Corns are. I have never had my Corn musk on me or anywhere, at least I haven't smelled it yet. But a corn or King is a really good chose for a child beginner. And it just depends on what color you want.
