You said "Superman was a bigger seller in the '50s, Batman was a bigger seller in the '60s."
Which is wrong. From the period 1960 to 1969, Superman sold millions more than Batman. Even if we're just restricting it to Superman magazine vs. Batman magazine. We toss in all the related titles and it's even more lopsided in favor of Superman.
1966 to 1967 don't make up "the '60s". Nor, did you specify that you weren't talking about Superman titles in their entirety vs. Batman titles in their entirety, which certainly is a relevant barometer of popularity.
If you want to say that at one point in the 1960s, one Batman magazine outsold Superman's namesake title for a short period, then fine, but by all reasonable standards Superman dominated the superhero marketplace of the decade. And it wasn't even close. That clearly was the peak of Superman's comic book commercial appeal and it's relevant to try to understand why that was.
