This and you can allocate prefix for services. Also you can do layer 3 access control because there is no NAT. Also NAT can get messy when chained. One very practical example is that if I am connected with SSH to a server, and connection is interrupted with a network gear config change for example, when it is back up, SSH will be still connected and might not even notice. With NAT, states can be dropped.
