I have no experience with ruby, but python's advantage is in strong typing. Try and add an int and a string and you'll get a type error, JavaScript on the other hand will do it though. While maybe allowing you to write more expressive code, it does mean that errors become harder to locate, and when dealing with larger applications, I prefer being able to locate errors quickly.
