An ArrayList is OOP 1.0 ,-) Just kidding. The handling of the ArrayList is much easier, that's right. But except for some places where we access the first and only element of the set we normaly iterate through the complete set. And: The order in the set/list is unimportant. And that's a good indicator to use an "unsorted" set with the additional benefit that an element can only be once in a list and not twice or more times like in a list.
