Depends on the kind of armor the knight is wearing in terms of speed and protection. Some armor can be lighter and easier to maneuver with for knights. As much as I'd prefer the knight to win since I've liked them longer, samurai seem to show more skill with a sword from what I've seen. It would be one hell of a fight, but I think in the end the samurai would win
samurai of course. theyre like cousins with ninjas... LOL.
even tho knights have heavy armors, a samurai can find a hole to kill them. not all of their body is covered anyways. armor and a big sword slows down their movement.
I'll vote for the samurai as they are more agile. If they both start off on horses then I don't see why a samurai wouldn't win. They can dodge the attacks from the knight and then stab them where the armour doesn't protect, like the eyes >_<
