Well, if we're doing comparative lists now, how can I resist?
Marvel movies that I consider good to great: X-men 2, X-men First Class, X-men DoFP, Amazing Spider-man, Iron Man, Cap. America First Avenger, Avengers, Cap. America Winter Soldier, Guardians of the Galaxy, Avengers Age of Ultron
DC movies that I consider good to great: Batman 89, Batman Begins, The Dark Knight, Superman Returns, Man of Steel (I should note before anyone gets too upset, I've never seen the Donner Superman movies, except bits and pieces of the really bad ones at the end of the series)
If we're including imprint titles, I really liked Kick-Ass and V for Vendetta, but I'm not really sure which company owns them.
Marvel TV shows that are good to great: Agents of SHIELD, Daredevil, Jessica Jones, Agent Carter (IOW, every tv show Marvel Studios has ever touched, really - so far, at least)
DC TV shows: The Flash. Every other DC tv show ranges from disappointing to unwatchable. And even the Flash tends to have significant issues every now and then.
I do wonder how many people bringing up tv shows from decades ago have actually watched them since they went off the air. Because I remember liking Lois and Clark when I was 9, too, but youtube clips pretty much prove it was an absolutely terrible show. It's also amazing how hard it is to listen to the old X-men cartoon show that used to be the center of my universe.
Anyway, DC comics vs marvel comics is fairly even, but by any other metric dc is clearly behind, and when discussing movies, dc is so far behind it's almost laughable, especially considering that DC had a multi-decade head start. And it's not really that DC can't make good movies. MS clearly has a better concept of how to work with these properties than WB does, but that's because MS is a clear outlier - WB is generally very comparable with the other studios that make these movies.
The biggest reason DC is behind is because WB simply does not appear to have any real confidence in the material. In the decades between Superman I and the Spider-man/X-Men successes that ushered in a new era of superhero movies, they never even attempted a Wonder Woman movie. They gave up on Superman entirely, despite the fact that his movie series was killed by terrible writing, not problems with the character. They took a successful Batman series and forced it into a happy meal mold that resulted in nippled bat armor and the bat credit card, because superheros are for kids. And apparently kids love credit card jokes.
Even after superhero movies became cool, they still pinned all their hopes on Batman and Superman, making only one other early attempt to give a different character a chance - and that attempt (Catwoman) was so ridiculously sabotaged that they were basically just throwing money away. And when they finally started accepting the fact that they were really going to have to have some more successful characters than just Superman and Batman, it still took them almost a decade to actually attempt Wonder Woman at all, because they still had more confidence in Ryan Reynolds fighting alien clouds with terrible cgi racecars than they did in people's willingness to accept a female hero (despite all evidence to the contrary).
