In the 30s & 40s, the audience was largely pre-pubescent kids and the stories reflected that in terms of sophistication. However, during WW2, a lot of soldiers got hooked, so more and more comics started appealing to a more adult audience with higher levels of horror, sex and violence, which caused the Comics Code to clamp down on all that.
As a result, the audience for comics went back to pre-pubescent kids in the 1950s, but with a growing segment of hardcore fans. Meanwhile, European comics could appeal fully to adult audiences and was able to outpace American comics by leaps and bounds in terms of craft and sophistication.
By the 60s, Marvel's deeper characterization and ongoing sopa opera with its more interconnected continuity had managed to retain those pre-pubescent kids into their teens and college years, which led to even more sophisticated writing and subject matter.
By the 70s & 80s, these former fans had now become the creators and writers themselves, so the comics became even more obsessed with past continuity and dealing with mature subject matter. However, it often dealt with that mature subject matter in a less than mature or sophisticated manner because these comics were based upon a foundation designed primarily for children. DC then started recruiting more and more British creators, who brought with them the greater sophistication of the European comics to the American superhero mainstream.
Once the direct market allowed comics to more fully embrace adult content, the one-two punch of Watchmen and Dark Knight Returns blew the lid off the concept of comics being for kids and both DC & Marvel's output has been a mixed bag of comics aimed at everyone from kids to teens to adults with wildly varying degrees of quality and success. However, it's undeniable that both companies have devoted most of their comics over the last few decades to appealing to their most hardcore readers, most of whom are men in the 40s.
Are the comics better or worse? That's all subjective.
