This will sound weird, because I'm down with there being like a zillion multiversal Supermen, versions of Superman, running around, meeting him in cosmic trippy team-ups.
Yes I'd like to see a redemption from how Superman-2 died in IC. But I'm really into the notion of there only being one Superman. Like, Golden Age, Silver Age, Bronze, Dark, Modern ... just one dude. Same dude. His timeline rejiggered, but not his Earth completely reset. Because invariably they just end up re-mining the classic continuity anyway. So it's definitely the same dude anyway.
People really dig on that storyline advancement that led to Earth-2 and all the "Classic Versions" of characters actually getting to grow a little older.
But I'm a guy who believes that Garrick, Nelson, Scott, Grant, and the rest, should all be evergreen and youthful and revived constantly like Batman and Superman are. Though I'm very cool with them being "older" than younger legacy guys like Barry or Hal.
