Goku Vs. Saitama, who would win?

Recently, the Reddit forum has reignited a classic debate among anime fans: Who would win in a fair match between Saitama, from One Punch Man, and Son Goku, from Dragon Ball? Both characters are known for their incredible power levels, which has led to divisions in the community over which of the two is truly the stronger.

Goku, the protagonist of "Dragon Ball", has been pushing boundaries over the decades, from his first training on Earth to his transformation into a Super Saiyan and, finally, his access to the state of Ultra Instinct, a technique that places him at almost divine levels. Goku has faced powerful opponents capable of destroying planets, galaxies, and even the universe, and his ability to outdo himself has been a characteristic trait throughout the franchise. However, Goku remains a warrior who constantly seeks challenges and rarely defeats his enemies with ease, preferring to enjoy the thrill of combat.

On the other hand, Saitama, the protagonist of "One Punch Man", was created as a parody of the invincible characters in the anime. His premise is simple: no opponent can withstand his power, which leads him to defeat any enemy with a single blow. Although the tone of One Punch Man is comical, Saitama is presented as someone with unlimited strength, and as the story progresses, his power seems to have no end, becoming an unstoppable phenomenon that bores Saitama himself due to the lack of real challenges.

But what is the opinion of the fans?

"After the last chapter, I feel that Saitama can beat Goku because of his infinite strength and how he keeps growing. He can travel back in time without creating alternate universes, destroy planets with a sneeze, and travel instantly with a fart."
"Goku defeats him effortlessly."
"Saitama no longer has infinite strength, only unlimited growth, something that any saiyan has. Goku defeats him before he can grow up."
"Goku almost destroyed the universe at the beginning of Super, and characters like Beerus only used a fraction of his power to destroy planets. Goku would win in his current state."
"Goku is not even the strongest in his own universe."
"Saitama continues to grow stronger and Goku will run out of transformations, eventually he will be defeated."
"Saitama is a joke character, inspired by characters like Goku. If the creators came together, Goku would probably win."
"Saitama would win after ten minutes, as Goku always holds back in front of his opponents."
"Saitama is written to always win, no matter how strong the opponent is."
"Goku can't travel back in time like Saitama, who would simply go back to the start of the fight to win."
"As others have said, Goku is essentially multiversal at this point. One of his achievements affected a five-dimensional realm, which alone surpasses what Saitama has shown. Goku has fought Jiren, a guy who transcends time, according to what Vados said, an angel who easily surpasses these two. So, until Saitama also transcends time and shows a multiversal or universal achievement, Goku continues to win."
"Can Goku defeat Saitama in one blow? Absolutely. Will he? No, he loves a good fight, he has never beaten any of his villains in one blow or been faster than them, he likes excitement."
"People don't understand what Saitama really is! He's a parody of dominated characters and winning is literally a characteristic of his character! He doesn't lose against Goku because it's written so that he always wins."
"Wow, so you're saying that doing 100 push-ups, 100 sit-ups, and running 100km would give you infinite strength? Wow, what a crazy anime story, while Goku has lifted more weight than Saitama and Goku was born on the planet Vegeta and Saiyans have no limits."
"Well, in my opinion, the achievements don't matter because the characters are written very differently. The narrative of Dragon Ball is that Goku faces opponents to increase his strength. The narrative of One Punch Man is that no matter how strong you are, Saitama is going to win with a single punch."
"No character will win against Saitama. Perhaps a character with reality-altering abilities could defeat him by removing him from existence. But that wouldn't qualify as a fight. Even that might not work on him because Saitama literally breaks the rules of physics."
"The only way Goku would beat Saitama is if you put 'conditions' on the fight, such as Saitama not being able to use his exponential growth because he is not emotionally involved or that Goku, completely out of character, defeats a base Saitama who has not had the opportunity to improve."
"Without a big handicap, there's absolutely no feasible way for Goku to beat someone who can theoretically go back to when he was a baby and just crush him like a fly. Honestly, all I would have to do would be to go back to the start of the fight before Goku raised his guard because the idiot never learns to keep it up."
