How do the power systems of DC and Marvel differ, and how does this impact a potential 'who would win' scenario?

DC's power systems often revolve around cosmic energies, alien physiology (like Kryptonian biology), and inherent powers bestowed by gods or scientific anomalies. Marvel's power systems tend to be more grounded, with an emphasis on superhuman strength, durability, and specific abilities developed through mutation, technology, or training. DC often deals with more world-threatening, cosmic-level events, whereas Marvel's stories frequently focus on more localized, personal conflicts, although they have scaled up considerably in recent years. This difference means a DC character might have a universal-level power, while a Marvel character might excel in a more specific area like energy manipulation.
