Basically, it comes down to each company having a "Big 3".

For DC, that is unquestionably Batman, Superman, and Wonder Woman.

For Marvel, it's a bit harder due to the MCU, but even still, Spider-Man and Hulk are definitely in there, and X-Men's long-lasting popularity as a film franchise (and as a comic beforehand) I think earns Wolverine that 3rd spot, not to mention that he (and the other 2) have the most clear matchups for Marvel characters, where neither Iron Man nor Cap has one that really stands out as immensely popular (beyond them vs each other which is both outdated and stupid).
