Knights for sure. Samurais have to be all secretive and crap because they are too scared to take them head on. :]
Okay, first off, knights were taken at the age of eight to begin training. That's damn young. Samurai started training around the same time. I think.... Anyways, Armoured: The knight would MOST likely win. All they'd need to do is get one shot in, and it would knock the samurai off his feet. Then *woooosh* done. Unarmoured: I would go with the samurai. The knights were in such good condition. So were the samurai, for sure. However they carried around that armour, and were in VERY good condition. The choice of weapon matters, of course, which is why I chose the samurai. FOR YOUR INFO! SAMURAI IS THE PLURAL AND SINGULAR FOR SAMURAI STOP ADDING AN "S" AT THE END OF SAMURAI.... Thank you.
The Knights can hardly move in that big clunky armor so the Samurai would definately win. By the way does anyone know why Ninjas used stealth? Because they were too weak to face the samurai head on and thats why the ninjas lost to the samurai. Well.. in my opinion
