Whereas Golden Age Supes was faster than a speeding bullet and more powerful than a locomotive, Silver Age Supes could extinguish stars with his breath and break the bonds of infinity by flying. Big difference. But when it comes to Silver and Bronze Age Supes, is there one? Whether it be in terms of power or otherwise.

It's more a difference in approach. When Mort Weisinger was editor throughout most of the Golden Age and the Silver Age, he basically made sure Superman was as wacky as could be considered kid-friendly. Hence the likes of Titano.

When Julius Schwartz became editor, he basically wanted to do the same thing Byrne did (take away all the "additional" elements of the Superman mythos, on the assumption that it was watering it down), and thus got first Dennis O'Neil and then Elliot S! Maggin and Cary Bates to tone down the weirdness and bring new stories and themes. Hence, the Bronze Age Superman was a lot less neurotic and more... thoughtful (that's not quite the word, but it's the best I can come up with right now). Also, he got rid of kryptonite, made Clark a news anchor, introduced Steve Lombard, etc.

In terms of power, Bronze Age Superman is basically a slightly more grounded version of Silver Age (because Schwartz insisted on his Superhero comics having some "scientific basis").

I see. Thank you for taking the time to answer this. Appreciate your well-informed post.
