I'm well aware of how much Byrne wanted to bring Supes back to how he was in the Golden Age, but by that point, the mythos had expanded so far beyond that, and the Superman and Luthor characters had been well established over the subsequent decades, that re-setting them to that standard seemed to me like a massive step backwards.
To get back closer to the concept it was meant to be by the creators, while also updating it for a contemporary audience was a massive step forward and improved sales.
There were a lot of barnacles that had accumulated on Superman in the Silver Age/Bronze Age. As John Byrne said, "
there's really nothing about the retroactive introduction of Superboy into the mythos that works. Aside from the contradiction of established continuity -- not a concern in those days -- the first issue presents us with Clark Kent in Smallville with Ma and Pa and a supporting cast all in place. No consideration was given to the fact that for this to work he would have had to have his "secret identity" before he became Superboy. He would have had to have adopted the "mild mannered", glasses-wearing, posture-altered persona for Clark before he became Superboy."

"One of the things that impressed me, as a kid, about Spider-Man was that Peter Parker was 15 or 16 years old, but he called himself Spider-Man, not "Spider-Boy". Something that Stan made good use of was that kids -- at least the ones I knew -- didn't want to play at being kids, they wanted to play at being adults. So there were no "boy" or "lad" characters in early Marvel. We had the Invisible Girl and Marvel Girl, but neither of them were really "kids" (Jean would have been about 16 or 17 in that first issue), and "girl" was just the term used then for anybody who was female. We even had "old girl" for women who were really past the term.
Starting out with no Superman already in place, young Clark would, I expect, have picked a less age specific name (than "Superboy")."

"The deathbed scene, wherein Pa Kent, before dieing, cautioned Clark that he must only use his great powers for the good of Mankind, when Clark had already been doing just what his father bid him to do. Superboy's adventures had made the deathbed scene not only unnecessary, but actually insulting. Pa Kent should be confident enough in the moral upbringing he and Martha had given Clark that he would have no need for that "reinforcement". I decided to go back to Seigel and Shuster and eliminate Superboy from my version -- but keeping certain elements by retaining Ma and Pa Kent as viable still living characters."

There were a lot of barnacles that had accumulated diluting Luthor's evilness. Lexor - the Bizarro world were people idolized Luthor and hated Superman, Silver Age Luthor's sweet nice Little House on the Prairie side with sister Lena Luthor, and Superman messing up poor Luthor's experiment and making Luthor bald. I'm glad John Byrne just scraped them away. I prefer Luthor to be an unsympathetic vicious sadistic bastard with a god-complex like he was in the Golden Age.
There were also a lot of barnacles that had accumulated diluting Superman's uniqueness as Krypton's Sole Survivor. In the Golden Age this was the standard. With Mort Weisinger's endless flow of Krypto the Super Dog, Beppo the Super Monkey, Kara Zor-El Supergirl, the Argo City citizens in the Survival Zone, the Kryptonian's in the Phantom Zone, and millions of Kryptonians in the Bottled City of Kandor in the Silver Age/Bronze Age one began to wonder if anybody really died when Krypton exploded.
Weisinger's Superman was also trapped by the ridiculously high level of his own power. Infinitely powerful and perfect is infinitely boring. If he doesn't have to struggle, and isn't at risk, there's no tension, and conflict isn't possible. As Denny O'Neil said "At one point he blew a star like you'd blow out a candle. Well, if the guy can do that how are you going to get conflict into the story exactly? The technical difficulties of writing about a guy who's godlike. How do you get him in trouble? Where's the conflict coming from?"
Not to mention the 'corrupt untouchable business mogul' had already been cornered by the Marvel villains, so Byrne's Luthor came off (to me at least) like a poor man's Norman Osborn or Kingpin.
Superman originally was a champion of the common man versus corruption of the law at the highest level. Luthor in Man of Steel was a return to that concept. Byrne's Superman arrested Luthor in Man of Steel so Luthor isn't completely untouchable. And his ability to exist above the law made things very difficult for Superman, and it brought some reality to Superman, some relevance, showing that the system is flawed and doesn't always work. It made Superman look like he wasn't perfect or living in a perfect world. I'm glad Superman couldn't legally keep him behind bars. It created tension, created a struggle to have Luthor actually hold his own against one of the most powerful men in the universe, despite having no actual Superhuman powers of his own.
And I know this sort of thing is subjective, but I always hated the 'cold, antiseptic' Krypton from both the Byrne comic and the Donner movies. One of the key elements of Superman before then (and now that they've re-established a lot of the Pre-Crisis stuff) was him trying to carve out his own identity by balancing his Kryptonian heritage with his Midwest upbringing. If Krypton was such an unfeeling dystopian world, why the hell would he even care about being from there? That's like someone escaping a dictatorship, only to go around flying said dictatorship's colors.
I don't like Weisinger's Krypton that the Silver Age/Bronze Age Superman pines for. The Supermope diminishes him. I wouldn't like and would be a little afraid of the Superman who says "Great Rao" and spends his spare time in a Fortress shrine to Krypton in solitude feeling like a "stranger in a strange land" on Earth. The Supermope diminishes him. Siegel's Krypton was not depicted as a Utopian society and was only depicted at the moment of its destruction, details of life there being unaddressed and frankly irrelevant to Superman's adventures on Earth. Siegel's Golden Age Superman didn't even know about Krypton. And Byrne's Superman also didn't even know about Krypton until years after he had been crimefighting as Superman. I prefer the Superman who is formed by the Kent's upbringing and views his Kryptonian heritage only as a curious memento of a life that might have been. Krypton is alien to him. The cold, antiseptic Krypton is far more believable and serves as a warning to not let ourselves become like that. There's a moral. Superman is fulfilled, secure, whose identity is solidly formed by his folksy human Kansas parents' values, without any desire to return to Krypton. He's generally upbeat and positive. He feels human because of his upbringing.
Adding the birthing-matrix nonsense into it, and calling him the 'Last Son of Krypton' makes even less sense, since he technically wasn't even born there.
He is the last Kryptonian, whether he was born on the planet Krypton or not is irrelevant. Also, the fetus has a heartbeat. Once that little heart starts beating the baby is alive. Anything that has a heartbeat is alive.
Anyway, I know that since there was never one official established origin story (other than a single panel in Action #1),
That single page prototype origin story published in Action Comics #1 (1938) had a passing motorist (singluar) find the child, who took him to a orphanage. Where, so far as anything indicated in the text reveals, he remained until he became an adult. He acquired the name "Clark Kent" from unknown sources, presumably from someone at the orphanage.
This is not an official established origin since it was altered and replaced by the creators Siegel and Shuster themselves with the Superman #1 (1939) origin that I've already posted where the Kents find him, name him Clark Kent and raise him giving him a loving home and family.
there are always going to be arguments over what the 'definitive' take on Superman is. But for me, neither the Golden Age or the Byrne comics do the rest of the mythology proper justice.
The Golden Age Superman mythology by creators Jerry Siegel and Joe Shuster is as close to the proper correct authentic version as there is, and John Byrne's version is closer to the Golden Age roots (while also updating him for a contemporary audience).
And for the record, I liked Birthright.
And I don't like Birthright. We are obviously fans of different versions of Superman. Over the years there have been radically different interpretations, different versions of Superman so each of us today has a highly personal view of Superman and favor those Superman stories that reinforce our prefered version, our Superman.
