Knights by far. This is easy. The Euros had better armor. Bigger stronger horses. Armored horses. Their heavy swords would knock the light weight Japanese ones aside & cut right thru that cheesy armor. Japanese has crap armor. Well made but poor design swords. Small light unarmored horses. The Euros were bigger & stronger. The English bowmen were best in world. Them shooting from greater range; while knights used better longer weapons to plow thru the Safari like tanks thru grass. Not even close. You could even give the samari some ninja, wouldn’t matter. Ninja were just assassins in pajamas with cheap weapons. The euros had assasins who could fold selves up into a box. Wasn’t really many of either.
