DC has had three female led superhero films out of the 25. Marvel has had none. Marvel's X-Men universe and the MCU have produced at least 28 films and none of them have starred women, including X-Men: Days of Future Past that swapped out a comic storyline featuring Kitty Pryde for Wolverine.

It's funny because that has nothing to do with this conversation or the argument I am making. This discussion is about potential, and which company has the greatest potential to promote female characters in live action, particularly in leading roles.
DC, in my opinion, is better position because it has better source material, has a stronger foundation in animation and television to familiarize the audience with its female characters over decades, and has shown more interest in investing in female characters in live action.
DC has led the way when it comes to female characters starting in the 70s with the Wonder Woman television show and its amazing success with DC Superhero girls. Since the 80s, DC has produced more female-led films than Marvel despite Marvel making more films than DC.
I don't think your claims are supported.
