1. Superman and Lois
Tyler Hoechlin got his chance to play the Man of Steel full-time in Arrowverse offshoot Superman and Lois. While technically a spinoff of Supergirl, the version of the title characters aren't the same ones we met on that show as Superman and Lois is set on an alternate Earth. Even though that wasn't made clear from the very beginning, the handling of Superman subtly hinted at it.
This version of Superman is, by far, the strongest we have ever seen on-screen. Not only is he a veteran superhero, he's a loving father with a family to fight for - something that makes him so much stronger 20 years after first donning the cape. He's also built up a bit of a threshold to Kryptonite, which we saw in the first season when the DOD agents attempted to subdue him with green bullets. So, yes, it still affects him, but he's capable of withstanding it for longer than his peers.
Something else he is capable of withstanding is near-death itself, surviving an attack from the Parasite, Ally Allston, which stole his powers, before recharging himself in the actual sun. That recharge single-handedly made him the most powerful version of Superman to ever grace any screen, as he was literally glowing with the power of the sun itself, quickly defeating a threat that seemed unstoppable and managing to separate two worlds that had been merged together in the process. All within two minutes.
A veteran who understands the superhero game better than anyone else, and one with a driving force of family behind him to ensure that he never stops fighting for a better tomorrow, Superman and Lois' Man of Steel is the ideal superhero and the most formidable version of the character we've ever seen.
