The two who would come out on top would be Grimnar and Dante. Both are considered the greatest warriors in the Imperium.

Still one hell of a battle though.

As for the Inter-Chapter history, don't worry, Ragnar has a shitton of plot armor (which is why he would win over even Cato Sicarius)

I mean, you got to when you have: Survived a horde of Chaos Daemons alone, Survived fighting with a Greater Daemon of Nurgle, Single-handedly taken down 20 Genestealers, dodged a Space Marine strike before he was an initiate, Tossed an ancient spear of his Primarch in the eyes of Magnus the Red, fought off several Rubric Marines, fought off hundreds of renegade PDF forces (No big surprise there, I mean, they're PDF :3) AND fought against another horde of daemons in the warp with no protection other than that of sheer balls-of-steel and the epicness that is the 13th Company.

Ragnar Blackmane = About as Sue as Ward can make the Ultramarines :3
