I don't even have to throw in Lois Lane and Jimmy Olsen. Superman, Superboy, and Action alone significantly outsold Batman and Detective. Toss in two highly popular spinoffs and Adventure featuring Superboy and the LoSH and it's academic.
Your point, which you're cherrypicking data to try to make a case for Batman being bigger than Superman in the 1960s, isn't really true when you look at the data, including the fact that the Batman magazine wasn't even monthly during a good chunk of that period.
You want to argue that a good chunk of the foundation for Superman's success in the 1960s was laid down in the 1950s, that's fair. But, given readership turnover, it's obvious that the 1960s Superman team was doing something right as they sustained their success while Batman's sales declined and needed a significant revamp. And Batman needed a revamp again after sales crashed post-Batmania. There's plenty to like of Superman in the 1960s, from Shooter's LoSH, to "The Death of Superman" and other imaginary stories, to "Superman's Return to Krypton" among the highlights. The fact that Superman remained immensely popular for a decade after the George Reeves series ended has to be attributed to the fact that readers to the time responded to the actual comics. They liked Superman then.
