Dc has more power houses than marvel. Take JLA vs The avengers. JLA practically everyone has powers except Batman and blue beetle being that he is basically iron man with the scarab being jarvis. But the avengers has many powerless great hero’s that would die first in a marvel vs dc battle. Honestly dc designs characters to be op like captain atom. He is said to be able to make each punch equal to the force and energy of nukes. That op af and only the strongest could beat him alone. I won’t lie though marvel has strong people too like sentry and blue marvel and anti man but of course dc has more people in that same playing field when it comes to strength.
