Alright, the matchup is here:
Dayne
> Deadliest Kingsguard of Aerys Targaryen's legendary group.
> Equal to Barristan, one of the greatest swordsmen in the lore's history...without Dawn. With Dawn, he has the outright advantage even over him.
> Defeated the Smiling Knight, considered "The Mountain of his time" in a pretty clear cut fashion. At one point even allowed him to change swords and the Smiling Knight was already bleeding from a dozen of wounds.
> Insert Jaime wank: "The sword of the Morning, who could have slain all of you with his left hand, while he was taking a piss on the right."
> Died in a 3v7 and there might have been some fuckery there on Reed's part.
> First pick by Martin if it was a trial by combact.
So, the guy's portrayal is absurd. Rhaegar defeated him in a joust but that doesn't mean much, Jorah Mormont also defeated Jaime Lannister in joust but would get opened from balls to brain if they fought. An actual 1v1 to the death is a different thing. Rhaegar was a scholar who only later decided to become a fighter because he read some prophecy in the books. He's not in the league of Dayne and got slain by Bobby B.
Daemon Blackfyre
> In his youth, many thought he would become another Dragonknight.
> He mastered all weapons of war, Eustace Osgrey considered him as good as any knight he had ever seen with those...but with Blackfyre he called Daemon "The Warrior himself" and considered him superior to both Ulrick Dayne with Dawn (one of the finest of his time) and the Dragonknight with Dark Sister.
> Had a one hour duel with Gwayne Corbray, a member of the Kingsguard who held a Valyrian sword. Some described it as "the greatest duel ever".
> Died to arrows.
The counterarguments against Daemon come from two things:
- "Eustace Osgrey was biased for him and might have exaggerated his abilities." It's not impossible, I guess. But Eustace admired great warriors. Yes, he followed the Blackfyre in the rebellion, but it's perfectly possible that he just saw things that way when it came to Daemon's ability and would have thought the same one way or the other. Leaving Eustace aside, like I had written above many believed that in his youth Daemon would have become another Dragonknight.
- His one hour long duel against Corbray. On here, again it depends if you buy into Daemon's hype and what you think of Corbray. If one believes Daemon was really that good, no exaggeration, then Corbray himself with his Valyrian blade is one the absolute best fighters of the lore. Someone who doesn't buy into Daemon's hype as much or Corbray's might want to argue that, perhaps, someone like Arthur Dayne would have made a shorter work of him. But I doubt Martin wanted us to see that Daemon/Corbray duel as an anti feat for Daemon lol. It's certainly possible that Corbray himself was just that good.
Overall, my position is that Daemon Blackfyre ~ Arthur Dayne ~ Dragonknight. All being true death matches.
Dayne is probably going to win this matchup by voting.
Thus today, I'll bet on Daemon Blackfyre, the Black Dragon
