Do you want a list or you want to discuss a bit about them? I am ready to talk about a few of my favorites. I loved your query.
I can understand stories of Superman dying. It is testing for any hero. During such tests the best of one's character is brought forward. Good writing can make such stories stellar.
Injustice guy is interesting? I never found that. Injustice is popular due to the gore and an interesting storyline. That guy was not interesting in my opinion. Those who think he was interesting may have a taste of seeing something dark or they maybe substituting dark for realistic. Grim and darkness does not equate realistic. I found that guy to be unrealistic. Christopher Reeves in films who would bring cats down from the trees makes complete sense if one uses a little common sense (becoming rarer nowadays). The only evil Superman story that i have both read and enjoyed, hence recall is Red Son. Dark Knight Returns is a Batman story.
From my limited reading(fan after Rebirth) i can bring up quite a number of issues. Without touching GreatKungLao's books (which i have read except for Earth One are fantastic) i can speak of a few books which are my favorites: Kingdom Come, Birthright, Man Of Steel, Issues from Superman Adventures( I have not read the whole run. It includes one arc of him dying. A personal favorite is #41). Hitman #34 "Of Thee I Sing", "Action Comics 775, Whatever Happened To The Man Of Tomorrow, Superman For All Seasons, For The Man Who Has Everything. These are some of the classics that i have read by now.
Some other great reads: Superman/Batman #1-6 (Public Enemies), Superman: Peace On Earth, DC One Million, Escape from Bizarro World, Superman #1(Yes. No 1 which has Action Comics #1).
There are a lot of books i have to read with eyes on JLA run of Grant Morrison, Geoff Johns' Braniac, Legion of Superheroes, Emperor Joker, etc. If i make a list of such books it would not be fair. You can find recommendations easily. (And i have not read them to discuss).
I have not read Pre-crisis except for the two mentioned as well as New 52 (Superman #39 is an absolute favorite. One of the four books i have read by now from that period). And Post Crisis is a work in progress with a humble beginning in Bryne era. I am loving almost every issue i am reading from there.
I would absolutely love to discuss those issues as well as why i find Superman fascinating. My favorite over the years were Batman and Wolverine due to some awesome shows and films. On reading comics i am finding Superman to be my absolute favorite. That by reading practically nothing if you consider almost 80 years of continuous publication.
The thing working against him is that many writers can't figure out what to do with him. Understandable considering that he has undergone a lot of reboots and continuity changes and an almost unhealthy obsession of going back to his origins again and again. Feel free to discuss this. A very interesting topic for a Superman fan.
