Contex? Do you mean since the TDK Triliogy, Superman II, Burton Triliogy? If you are talking since the creation of the MCU then fine, I agree. If you are talking since the creation of movies and television then DC's output far outstrips Marvel's on TV and movies. Possibly also in quality. Including imprints owned by the companies and it is not even a close contest on quality films by each company. I get frustrated when it seems like fans believe the world was created when the MCU began. Everyone acts like DC has never been successful with films or tv and that assumption is just plain wrong. Instead iof the building reference I saw it is more like DC is New York City (an old eastablished city with problems, needs rejuvenation) and Marvel is Dubai (New, innovative city but one who's obvious problems are overlooked due to freshness and the innovations that it has contributed.)
Last point as far as quality- DC films have been nominated for 27 Oscars and won 5. Marvel Films have been nominated for 10 and won 1.
