OP characters doesn’t make DC boring, you’re just a casual MCU fan who never read comics before. Seeing them struggling to hold back in order to live a life among frail mortals and always keeping them safe from outer threats as well as from their own powers makes DC comics interesting. On the other hand, the idea of a mortal hero going against a powerful villain and the hero giving his everything to beat the villain and save the people is cliched and boring. This makes DC cool and Marvel boring.
