DC's advantage at the time was having Batman 1989 and Batman Returns and then having Timm, Dini, Burnett and the rest creating a pretty high quality cartoon and then controlling the direction of the cartoons most of the time (BTAS/Adventures of Batman and Robin to Superman TAS to New Batman Adventures to Batman Beyond to Static Shock to Justice League to JLU). This was a consistent storyline that spanned from 1992 to 2006.
Marvel at the time was trying to make deals with as many different people as possible so this came with some problems such as rights for characters being with other people or different productions not gelling together
Like for instance, Saban handled the X-Men, Silver Surfer, Spider-Man Unlimited, Avengers United They Stand cartoons, season 4-5 of Spider-Man 1994, but weren't involved with the Fantastic Four and Iron Man cartoons.
Then in 1996 Marvel went into bankruptcy which disrupted the production of some cartoons (Silver Surfer got canceled and Captain America got shelved as a result)
And then in the 00s things got more scattershot
X-Men Evolution was at WB but was a Marvel production.
Sony had the rights to animated Spider-Man cartoons and put out MTV Spider-Man and later Spectacular Spider-Man
F4: World's Greatest Heroes was also a Marvel production
Wolverine and the X-Men was a Marvel Studios production but only lasted a season
Then there was Super Hero Squad which did its own thing but couldn't use Spider-Man
Then you have Avengers EMH which felt like it could've been the start of Marvel having their own answer to the DCAU.
Then you have the Disney era which was mostly aggressively mediocre and forced synergy at times. I think X-Men 97 and Moon Girl & Devil Dinosaur were the only cartoons from this era where I felt like they were trying.
