Say, it's 1985, and you were given the opportunity to do what you want with Superman. What would you have done?
This is my own fantasy, feel free to do your own....
I would have kept the Silver Age Superman. I would have accepted Kara's death, in CRISIS, and used it to give some depth to Superman, as Bucky's death (until recently) gave depth to Captain America. In fact, I would have slowly, over the course of a year started getting rid of other survivors of Krypton.
You see---and I can't believe I'm saying this---to a certain extent, I think Byrne had a good idea, making Superman the lone survivor of Krypton. It's hard to feel it's a tragedy when literally millions survived. I just hate the way he DID it. Elliott Maggin wrote a good story about returning Kara's body to her parents, wring the heartstrings---we have a chance to get some depth to the character, and instead, Byrne makes him FORGET KARA EVER EXISTED?

I think Moore's ending for Krypto was quite good. I think Krypto should have died defending Superman, and have us see a scene where Superman was crying over Krypto, his beloved childhood companion and pet. Have Krypto's death MEAN something.
Then, have Superman check in the Phantom Zone---and be startled to see it depopulated. All the criminals cleared out....
Find the dead body of Beppo, the super-monkey, in Africa, and wonder what could have killed Beppo....
And then have him wait for the next time Rokyn/Kandor is supposed to enter our dimension---and have it not show up....
That way Superman is left EFFECTIVELY the only Kryptonian, but with a maddening mystery on his hands. That way it doesn't negate the appearance of the Phantom Zone and Rokyn in the Legion, (we can assume that Rokyn and the Phantom Zoners have been captured/diverted, not really killed---but SUPERMAN won't know that, thanks to the post-hypnotic suggestion that leaves him largely ignorant of his future-knowledge) but leaves him wondering who murdered Beppo, who's getting other Kryptonians---and when will they come for him?
I would have moved in Lois and Superman's relationship, but not get them all the way to marriage. Have Superman discover, not his long-awaited way to give Lois full super-powers, but to make her at least as INVULNERABLE as he---which is all they need to protect her against his enemies, right?
They think. So they get engaged....
Only to have Brainiac show up, put Lois in one of those impenatrable force shields of his, and TAKE HER AWAY to another part of the cosmos. For us to occasional see the invulerable Lois, beating on the barrier, begging for Superman to come save her....
But she could be anywhere in the universe....
Good luck, Kal. We'd see him trying to find Brainaic, but unwilling to leave Earth completely undefended, even for Lois....torn in two by duty and love...
I'm also a fan of the Golden Age Superman and the lower power levels. I liked what Denny O'Neil did in the "Sand-Superman" sequence trying to lower his power, but I hated it when Superman comlained he could ONLY leap tall buildings with a single bound---geez, I can't even leap ONE building. (Unless it's an anthill.) So I'd have some enemy like the Parasite succeed in draining Superman of MOST of his powers, but Superman breaking free soon enough to retain the 1938-level powers, and have about six months of adventures at THAT power level before his power builds back up....
What about the rest of you? What would YOU have done?---Al
