A considerable advantage would be knowing that you shouldn't use a linked list in most scenarios. The next best would be understanding that there are many different ways to do "linked lists", and it's important to control the choice. Software dependencies have a huge cost. The next best advantage would be recognizing that if you need to reverse a linked list in practice, you're probably doing it wrong. Writing a linked list implementation isn't hard. There aren't many things that are hard to implement. What's hard is making good decisions what to implement. No library can help there.
