Particulars change, but the basics always are the same. The problem is when the stories are replaced by eventsd and bad ideas... and you have the '90s Superman. Metropolis destroied, young Lex Luthor, the death of Clark Kent... No, thanks.
You know, it's funny, I think the opposite is true: Superman in the 1990s was an improvement over Superman in the mid-to-late 1980s - at least in the sense that the high points were higher.
Roger Stern told space opera stories introducing Maxima, and his magnum opus, "Panic in the Sky," featured an old school Superman that was a breath of fresh air after the very earthbound, Spider-Man lite Wolfman/Byrne tales. Then we had Louise Simonson's Superman stories featuring the incredible Riot (a one-man crime spree).
The post-Byrne years (1988-"Reign of the Supermen!") aren't bad. I have read various good stories in that period, like the "Krisis of Krimson Kryptonite" storyline or one of my favorite post-Crisis stories, "Crisis at hand". The worst arrived later! The long haired Superman, the destruction of Metropolis, the death of Clark Kent (urgh), the whole "Luthor young, then old, then young again thanks to a demon" matter... Sigh. I liked the Electric Superman saga, though, even if it has been too long. It was a sort of rule in those years: storylines were long, infinite! I prefer the following years, when Berganza arrived with Loeb and the others.
Sure, the nineties gave us arguably the worst stories in Superman's history, too, with an endless string of vapid villains: Conduit, the Cyborg Superman, La Encantadora....but still, at least it was all done for reasons apart from shock value and "this is NOT your father's Superman!"
Guess what? My father don't like the '90s Superman! Yep, that's NOT his Superman. He, who used to read the Man of Steel in the 1950s, consider all that stuff a mountain of junk.
