These are both long, dark shoujo series from popular mangaka, but that's not where their similarities end. Both X and Angel Sanctuary have complex, twisting plots full of conflict on a large scale. Each has a large cast of developed characters that have personal issues and could stand a few therapy sessions. Finally, in each series destiny comes into play to some degree.
