I'm not making a claim of majority/minority anything. I can't delve in so far as to get down that nitty gritty, no fan can, so I'm not going to try with blanket statements like that. We just can get a general gist, and in that regard sales are largely negligible between the two versions. I take that over online articles. So it suggests far more that you can make big changes, that post-Crisis-like status quos are NOT mandatory to keep things going for Superman. In the end there will be people who hate certain things and they will be loud about it but that's all it is, that's how we are as fans. Its far more simply about quality of writing, not whether Superman is young or old, not if he's married to Lois, not if he's wearing a classic costume or something a little bit altered, etc. Bringing back the old version entirely doesn't prove the opposite. Its in reality classic specious reasoning. Looking closer and at the trends of how DC operates in its modern era, it came back because when the DCYou failed line-wide, they needed another spark relaunch and that was the opportunity for the older talent in the company who didn't like the new Superman to pitch their ideas and it was accepted. DC saw widespread discontent then, again linewide, and it affected everything to varying degress and it was new pitch time for everyone. Superman got outright replaced back because of guys like Johns and Jurgens whom it was simply turn to get their way, really. That's not a knock on them necessarily, that's just how DC works for better or worse (usually worse). Someone gets their way for one initiative, internal discord and bad direction drops things eventually to the point they need a new relaunch, and someone else gets their idea in. Superman's changes were deeper than a lot of other characters, so they went deeper with the changes the next time, and one of the creators involved deeply hated the prior changes. In the end those are the main factors why the replacement happened, Its not nearly as simple as "New 52 was clearly universally hated by readers and that's why he was the only character in Rebirth outright replaced".
