Top 3:
1. Dead Superman (or maybe they did him a favor?)
2. Mullet Superman
3. Keith Giffen Superman (DC Comics Presents featuring the Creeper)
Ok, this has been getting to me for some time now.
It wasn't a mullet.
It was never a mullet.
A mullet is defined as very short in the front and long in the back (business up front, party in the back so to speak).
During that era Superman just had long hair. When he was Clark it was slicked back and pulled into a ponytail. You can't do that with a mullet.
Just sayin'.
