One Piece : Why is that luffy better than our luffy

The scene was set at the Summit War, when an unexpected presence burst into the live stream! The person drawing everyone's attention? None other than Luffy, captain of the Straw Hat Pirates! Two Luffy's had appeared—one dressed in white, the other in red. Both were online! The Luffy from the original world: carefree, brimming with energy, but often reckless. Though he was free-spirited, during the Summit War, he could only stand helplessly by as he watched his brother fall before his eyes. Then, there was the Luffy from the parallel world. By age three, he had already learned the hard truths of survival, setting out on a daring adventure at a young age! By seven, he had mastered Observation Haki. At nine, Conqueror's Haki. He set sail at fourteen, and by fifteen, he had awakened Gear Fourth! Not only did he push himself to the absolute limit, but he also constantly pushed his crew! Zoro: “I can’t afford to relax for a second, or else Luffy’s swordsmanship will outpace mine!” Nami: “The captain knocks on my door every night, and in three months, he mastered every navigation skill I had!” Buggy: “How did I end up with the honor—or misfortune—of supporting not just one, but two generations of Pirate Kings...” During the Summit War, Luffy stands over Akainu, foot pressing down. "I gave you a chance, but you've wasted it!"
