Best Supergroup?

Is Audioslave the best supergroup? I worked at a record store when this came out. I remember being super apprehensive about it. I think I was still mad Rage broke up. I listened to it, it was good. When people asked me about it, I said “Well it sounds like if Chris Cornell was the lead singer of Rage.” IDK maybe I thought it was too commercial. But it’s an absolute banger and has aged well IMO.

‘Shadow on the Sun’ absolutely crushes.
