I feel like both comics and manga/anime have the same problem. Both objectify women and put them in submissive roles. However, manga/anime's genres have various niches which appeal to women and are more abundant than comics.
As for diversity in audience, I have to say manga/anime has more female readers due to huger fanbase in Shonen which has bishonen characteristics, otome game adaptations, yaoi/yuri manga, Josei, etc
Sorry for being vague, I was referring to the Manga equivalent of one shot. A one shot in Japan is a chapter published in a manga anthology magazine. In rare cases, they do get a tankobon release example Mario by Kishimoto.
