From any variation, what is your favorite Legion of Super Heroes storyline.
Mine is pretty much a cliche' but it's definitely The Great Darkness Saga. I loved the mystery of who the Master of Darkness was, the Legion leader battle, the groups working in different areas, the great reveal, and the final battle. Plus, the creepy threat made by Darkseid at the end. The writing, Giffen's incredible art, and the pacing all made for a phenomenal story.
