What are the differences in the representation of diversity and inclusivity in DC versus Marvel comics?

Historically, both universes have faced criticism regarding the lack of diversity. However, in recent years, both DC and Marvel have made efforts to improve representation, introducing more characters of different ethnicities, genders, sexual orientations, and abilities. Marvel has arguably been perceived as slightly more proactive in this area, but both continue to evolve and face challenges in creating genuinely inclusive stories and characters.
