Yep, IDW collections. Of the material produced before the 70s, I think my nostalgia from discovery will always make the newspapers best to me. But I can't help expecting to like the golden age more than what I know from feedback.
The thing that interests me about the Bronze age being popular is how non rough and tumble he was. The Fleischer cartoons are enormously popular, maybe the most beloved of Superman in regards to other media. And yet quite different from what he'd become by the point of 40 years later.
