The Witcher vs. sword-fight gauntlet

The Witcher is armed with his long sword and a secondary long dagger. Fight is purely physical, he's not allowed to use any of his magic. He gets healed after every round. How far does he get? Assume all weapons are made of similar steel/quality.

1. The Bride - armed with katana and tanto
2. Dread Pirate Roberts - armed with rapier and dagger
3. Leonidas - armed with sword and shield
4. Achilles - armed with sword and shield
5. Prince Nuada - armed with spear
6. Legolas - armed with twin swords

Loses to all not sure about 2

Achilles is the best sword fighter to date on screen. The only reason Leoglas and Prince are even in his category if because they are enhanced metas.

Definitely defeats 2, Wesley has shown absolutely nothing that gets me convinced he could even give Geralt a good fight, he may very well take both him and Inigo by himself, he might beat Achilles and Nuada, Geralt was shown to be wayyyyyy more skilled the Hector, and I never found Nuada THAT impressive in the skill department, especially considering what Geralt goes up against.

Leonidas, The Bride, and Legolas are god-tier though, and they probably beat him solidly.

In terms of pure skill he's probably a bit better then everyone on the list, but he loses the ones I mentioned because they're way above him physically and Geralt usually picks off Fodder and monsters while The Bride is taking down like 30 skilled swordsmen by herself.
