The Virtual World arc is easily one of the strangest throughout Yu-Gi-Oh!'s entire run. Smack in the middle of the acclaimed Battle City arc of the show, the Virtual World sends the entire crew into Noah's virtual land, with the Big Five mounting their revenge on Kaiba and the rest of the crew.
While each member of the Big Five gets a chance to duel in this arc, none of them do particularly well. However, there are certainly members of the group, along with Noah, who have better dueling skills than others. Out of every member, Crump easily takes the cake as the worst of the group, but who fares best?
Crump
Crump takes the form Nightmare Penguin in his duel with Tea, which gives all of his water monsters 200 extra attack points. This is compared to Tea's cool Deck Master, Dark Magician Girl, who she is able to telepathically communicate with and use to draw cards from her deck, which is in a league of its own compared to Nightmare Penguin's effect.
Beyond that, Crump uses an array of weak water and penguin monsters who don't do a thing to Tea, a non-duelist character who manages to knock Crump out with relative ease. Crump never stood a chance, and his bad deck was one of the main reasons why.
Johnson
Johnson's Deck Master ability allows him to pay 1000 life points to destroy all opposing monsters and inflict 500 points of damage for each one, which is an astounding advantage, and he does manage to almost defeat Joey a few times throughout their duel. Johnson is a fine duelist, but he has one particular downfall that not many other characters in the group have, he actually cheats in his duel.
Johnson uses his powers in the Virtual World to reroll Joey's dice cards in order to benefit himself, which causes Noah to disqualify him once he notices the discrepancy. However, Joey allows the duel to proceed and still manages to wipe the floor with Johnson, which leaves him barely a better duelist than Crump.
Gansley
Yugi fights against Gansley in the Virtual World arc, who takes the form of Deepsea Warrior as his Deck Master. Deepsea Warrior allows the player to tribute two monsters in order to turn an opposing attack back to the opponent, which is a tough ability for Yugi to overcome.
Despite this, though, it doesn't take Yugi long to figure out a strategy to defeat Gansley, which he does with the help of his own Deck Master, Kuriboh. Overall, Gansley isn't too bad considering he went up against Yugi and actually put up a fight.
Leichter
Out of all of the Big Five members, Leichter had the best senses when it came to picking a Deck Master, as his choice of Jinzo allowed him to disable and destroy all of Kaiba's trap cards, 1/3 of his deck. This put him at a huge disadvantage from the word go. Of course, Kaiba isn't one to be defeated easily.
Leichter had a great strategy when it came to cards like Injection Fairy Lily and Satellite Cannon, but unfortunately, he was going against Seto Kaiba. If he had gone against one of the weaker duelists, he almost certainly would have overpowered them. Perhaps he could have even defeated Yugi, who didn't have quite the right deck to go against a deck like Leichter's.
Noah
Noah is a good duelist, but he has a few issues that keep him from taking the crown from the Big Five, unfortunately. Just like Johnson, Noah cheats in his own duel, using Mokuba as a shield to force Kaiba to stop one of his attacks, which goes to show that he's a coward when it comes to dueling.
This also impacts the duel significantly, as, if this was how Noah was going to play, Kaiba would have never been able to defeat him. Additionally, during his duel with Yugi, he was turning one of his friends to stone each turn. Noah had a strong deck, a capable Deck Master, and knew how to pull off combos. His refusal to simply use his skills rather than outside forces knocks him down a peg when it comes to the rest of the Big Five members.
Nezbitt
Nezbitt made the correct choice to go against Tristan, Duke, and Serenity in his duel - the three were an absolute trainwreck together. Serenity sobbed through half of the duel, and Duke was the most experienced duelist of the three, which was saying a lot. Nezbitt then used a Deck Master that allowed him to inflict consistent burn damage to his opponents, which is smart in a format where the starting life points are only 4,000.
His strong monsters also allowed him to consistently damage his opponents and keep them on the back foot. Nezbitt is the only character of the Big Five and Noah to actually defeat a duelist legitimately, no cheats required. While the bar for his duel was a bit lower than some of the other members of the Big Five, he chose right and employed a strategy that allowed him to take control of Tristan's body, something no one else managed.
