Wang Yu already had a massive build so with his long pole, his reach was much further than Zorro's katana.
In terms of long weapons, the further one was from the opponent, the easier it would be to attack and defend.
Moreover, there was a significant difference between swordsmanship and pole art. While swordsmanship focused on using strength to break through the opponent's defence, pole art focused on coupling strength and gentleness.
The technique behind this skill was exceptionally difficult.
As a respected master of kung fu, Wang Yu's wielding of polearms was naturally at the pinnacle of greatness. Being able to move about nimbly, dodging and weaving to attack and or defend. Whether it was his explosiveness or control of strength, he had mastered it to perfection.
