On modern CPUs most times liked lists are the wrong data structure to use. They are slower, use more memory, can be less handy and less safe. There are few situations where a single/double linked list is better, but they are quite uncommon (for example when you have often to add/remove items from the middle of a sequence and you can find such points quickly, this happens for example in the dancing link algorithm).
