hmmm...this'll be a quasi-bump, since I don't have a definitive answer.
Juggs power is magic-based....that's a problem for Supes. The only thing keeping me from being able to truly answer this is a lack of knowledge about Darkseid. I know Surfer's a badass and I'd favor Juggs over Supes, so I'll go with team Marvel unless someone can convince me that Darkseid would be able to handle one or both of them.
