Unfortunately imgur is still blocked on my work computer, but I do have this old post from a convo I had with Jason Czeskleba covering my favorite Silver Age Superman tales --

That was fun. What would be on your list?
It's tough, since I'm not as well-read as you in Superman... I'm making my way through them, but I have literally hundreds of issues to still get through. For our purposes here I will include the stories I think are the most entertaining, rather than milestone issues included out of obligation. If I were compiling a real book, I'd make more of an effort to capture all the most distinctive elements of the Silver Age Superman's universe -- a Mxyzptlk story, a Jimmy transformation story, a Krypto story, etc.
As you've pointed out, I have a massive Edmond Hamilton bias -- not intentional, I never knew who wrote these stories, but I am just going with the ones I truly like the most. I also have more Imaginary Stories in here than I should, but again, just going with what I enjoyed most.
All that said, there's some issues you included that I'd consider "musts" that I'd include --
The Story of Superman's Life by Otto Binder (Superman 146)
The Last Days of Superman by Edmond Hamilton (Superman 156)
The Showdown Between Luthor and Superman by Edmond Hamilton (Superman 164)
The Team of Luthor and Brainiac by Edmond Hamilton (Superman 167)
Superman in Kandor by Jerry Siegel (Superman 158)
Superman Under the Red Sun by Edmond Hamilton (Action 300)
The Death of Superman by Jerry Siegel (Superman 149)
Superman's Return to Krypton by Jerry Siegel (Superman 141)
The Amazing Story of Superman-Red and Superman-Blue! (Superman 162) by Leo Dorfman
And then mine --
The Superman Of 2465! Saga by Edmond Hamilton (since they didn't take up entire issues, I will cheat and list Superman #181 and Action #338 and #339 as one story): In the year 2965, Klar Ken T5477 takes over the role of Superman from his father, a role passed from father to son since the original Superman 1,000 years before.

The Danger of the Deadly Duo! by Jim Shooter (World's Finest #166): When Muto teams with the Joker of 2967 to battle Superman, the last descendant of Batman takes up the cape and cowl to help Superman and get revenge against the Joker, who's father killed his father.
