Both have really good characters.
DC: Superman, Nightwing, Hawkman, Doctor Fate, Superboy
Marvel: Deadpool, Prof. X, War Machine, Spiderman, Franklin Richards
Both have really good teams.
DC: Justice League of America, Legion of Superheroes, Young Justice
Marvel: Future Foundations, Illuminati, New Avengers
Both have had amazing storylines.
