Superman can absolutely take that punch, he might be hurt,he might even bleed but he is absolutely not dying nor is he severely injured by it nor would it be some kind of game changer.
I am 100% confident Supes could get hit by that, get up, and then work the ever loving shit outta Hulk. I don't like Superman either but I'm not gonna low-ball the shit outta him. That punch was impressive but it was probably equivalent to Supes crashing into that mountain. Maybe a little more. Even if we say it was twice the force, he's still getting back up.
