Well it's clear the OP has the answer to his question.
One thing I will say is its purely subjective. Outside of Morrison's run and Pak's non crossover stuff,i never found myself all that invested in New 52 Superman. I tried. Honestly I did. There were times I loved the guy. However much of the time , looking back,i was indifferent.
I hate how they brought REBIRTH Supes in.... but I can't deny that I find myself far more invested in this guy,especially in the SUPERMAN book. That comes down to the writting, which is again,subjective.If Nuperman was consistantly written,i would have felt the same way I guess as the OP does. I'm less attached to a specific version of the and more attached to good stories. All subjective.
I've been a reader 25 plus years,so I've felt what the OP does. preFlashpoint right around the reboot was the time where I'd gotten to that point where I was thinking " this ain't Supes.".
