Rather than checking lengths or types of data, we use the isDirty()

<cfif len(User.getUserId()) and User.getUserId()>

The way I understand it is, you can do something like...
//try to load a user
User.load(UserId = something);
if (User.isDirty()){
//you have a new User record on your hands
}
else {
//User is NOT isDirty() so you have an existing User on your hands
}
