In terms of strength and stature, Mihawk is among the elite One piece World.
His skill with the sword is said to be unparalleled; however, that certainly doesn't mean that no one can match him in swordsmanship. In fact, there are certainly several characters stronger than him One pieceand at the same time swordsmen who can take him down.

Vista Flower Sword
-
Commander of the 5th Division of the Whitebeard Pirates
-
Haki Type: Armament, Observation
Flower Sword Vista is the former commander of the 5th Division of the Whitebeard Pirates and has faced Mihawk once before in the Paramount War Arc. Of course, it goes without saying that Vista is not as strong as Mihawk and that the difference in strength between the two individuals is absolutely huge. However, Vista is still a very skilled individual who cannot easily be outdone.
Even Mihawk came to acknowledge his sword skills, and that's saying a lot. The battle between Mihawk and Vista at Marineford ended in a stalemate. In fact, Vista did incredibly well against it. Even the fans didn't see the full power of Vista. That said, we know he uses powerful armor and Haki observation, and together he can definitely give me a matchup to enjoy.

Roronoa Zoro
-
Straw Hat's strongest officer
-
Haki Type: Armament, Observation, Conqueror
Swordsman of the Straw Hat Pirates and the strongest officer in Luffy's Yonko crew, Zoro is a force to be reckoned with on the seas. Even though he is not at his peak yet, he is still strong enough to give Mihawk a great challenge and even injure him in battle.
Zoro is a user of all three types of Haki and continues to mature at an incredible rate. Fans have seen him climb higher in terms of power with each passing arc as he has yet to meet his goal. When it comes to just competing with Mihawk, Zoro can certainly provide a fantastic battle and easily impress the greatest swordsman.

Fujitora
-
A powerful naval admiral
-
Haki Type: Armament, Observation
Fujitora is a naval admiral and just because he is, we know he has a 3 billion bounty on his head. In terms of strength, we also know that Admirals can fight Yonka, even if they can't defeat them. This puts Fujitora in a somewhat similar range. Of course, his use of the sword is not traditional.
He uses gravity with his Yakuza Kasen sword, so he shouldn't technically be considered a candidate for the strongest swordsman in the world. Still, he is a swordsman and someone more than capable of matching Mihawk in battle. He's incredibly powerful, and his Devil Fruit makes him a resourceful fighter with unmatched abilities. Combined with his brilliant use of Haki of Armament and Observation types, we know for sure that Mihawk would not have an easy time against him and would relish the challenge of the blind admiral.

Saint Ethanbaron V. Nusjuro
-
A mighty elder
-
Haki Type: Armament, Observation, Conqueror
Recently, in the Final Saga, Oda introduced the Elders to the fans and from them, St V. Nusjuro was revealed as a mighty powerful swordsman. He wields a top class sword called the Shodai Kitetsu and at the same time wields tremendously powerful Haki that is equal to or greater than a Yonko.
Fans are sure to know that Zoro has tremendous strength and skills. He also has the Yokai Bakotsu ability which gives him incredible speed while also being able to freeze individuals. On top of all that, he's an immortal being who, despite being damaged to the core, just keeps coming back.
As such, there is absolutely no way Mihawk can easily defeat Nusjur, even if his sword skills are better than his, which is also debatable. Since Nusjuro didn't get involved in the goings on in the world, he could very well be stronger than Mihawk in One Piece.

Shanks
-
A powerful emperor with the strongest Haki
-
Haki Type: Armament, Observation, Conqueror
Portrayed by Oda as the strongest living Haki user at the moment, Shanks is a monster anyone can handle and fight. He and Mihawk have a huge rivalry that dates back many decades. This rivalry was uneventful, meaning that neither was ever declared the winner.
Shanks is a great swordsman; however, his use of Haki is what makes him truly special. In terms of skill with the blade itself, Shanks isn't as good as Mihawk. Overall, though, she's still stronger than him thanks to her Haki. If these two were to go all out, Shanks would definitely win here. When it comes to sword skills, Mihawk is better.
