The knights were strong warriors. However, they were much more than that. They followed the code of chivalry, and were perfect role models. They defended the weak, helped the poor, and had a strong religious belief in Christianity.
The knights were stronger than samurai due to the fact that they had much stronger weapons and armour. Now, you may argue that the weapons and armor were heavier than the samurai's, causing them to move slower, and that the katana has a sharper cutting edge than the knight's long and broadsword, but I strongly disagree. The armor were jointed and plated to allow for easy movement. Even during peaceful times, the knights would train in their armor to build the stamina and strength to use it. Not only that, but their iron plates were much stronger than the leather samurai used. Not only that, but once wet, the silken cords used to keep the armour together will more than double the weight of the samurai's armour. The katana is much sharper, but this is not lways an advantage. In fact, it is a HUGE disadvantage. In battle, you would want an edge not to sharp to chip or dull, but not too dull to not cut. The knight's swords acheived this, while the samurai's blades would chip after just 1 swing, especially into the knight's armour.
The knights were also stronger than samurai due to their specialization. Knights often chose to specialize in no more than 3 weapons, so that they can master them. The sword and lance were often the most popular choices. However, they also had flails, maces, clubs, and battle axes to use. This specialization in close-range combat led them to be able to easily defeat the samurai. Though some may say that their specialization in close-range combat was a disadvantage, I disagree. The samurai may be able to shoot arrows from long range, but the knight, and even the knight's horse, was completely covered in plate armour. Not only that, but the knights had a chain mail to cover the cracks, and even a shield. Shooting arrows at a knight would be like using a machinegun against a tank. Sure you might scratch the armour, and sure you might look good, but you, in reality, would be doing no damage at all.
The knight's chivalry was very similar to the samurai's, but far superior. For instance, after losing a battle, a samurai would perform ritual suicide. However, a knight would be given a
second chance. Not only that, but the knight's practiced Christianity rather than Buddhism. Buddhism taught about reaching Nirvana, which is something only you can benefit from, while Christianity teaches about love and helping others, even your enemies. Because of this, I believe Knights are far superior to samurai.
Knights are better than samurai. They follow chivalry, have strong armour, and specialize in close-range combat. They are far superior to the wannabe samurai.
