I am not a comic book guy, so I can't speak on the accuracy to those, but from what I have seen, Marvel stories are FAR superior to DCs. Batman might be the lone character that can somewhat compete with Marvel characters, maybe Superman a little.
But as I ranted about last year on the SH lol... DC villains are fucking awful and dumb.
WW84 - a wishing stone created by a greek God
WW - Aries... a greek God.
Aquaman - Ocean Master (say that name out loud and tell me you think it works lmao, its fucking dumb) However, Patrick Wilson is a solid actor.
Flash (CW) - Reverse Flash.... well that is thinking outside the box.
Shazam - 7 Deadly Sins.... omg c'mon.
Green Lantern - the color Yellow
Justice League - Steppenwolf whose entire life goal is to destroy all life.... fucking stupid. So bad.
The premise of some is just dumb, the name of others is incredibly dumb. And there are glaring holes story-wise in each of them. DC needs to revamp with all new stories and villains.
Captain Marvel is pretty bad... like REALLY bad, but DC makes it look decent.
