The Medieval European Knight vs. the Feudal Japanese Samurai?

The first meeting would be nice. Surprises from everywhere. But I have no doubt that both sides would quickly adapt & change their methods to mathc their opponent. If differences are THAT numerous, that's also because both sides never met in engagement. For those new to this, you should read this

I really liked that article, thanks for posting it!

Em-mass I believe the knight and its deverstating lance charge.
Man vs man would depend on the skill and experience of the fighter.

Of course one can look at the mongal invasion and the engenious tactics used played far greater effect then the qualities of indiviual fighters.

i think the lucky one survives.in battle there is no good or bad there is just the luck you are not the one who died
