Too Long; Didn't Read
The unique difference that comes to my mind when compared with Git is that we can have any numbers of private repositories but not in Git whereas we can only have one in the later. If you don’t want to share your code and make it confidential, you can go for BitBucket. If you don’t have an account yet, you can get one @ <a href="https://bitbucket.org/" target="_blank">https://bitbucket.org/</a>
