They are very intersting to watch and among the comments there is one which I think in general should stand out to all "cross training":
zvyej: who won?
zukuru: on experience ? .. I think both - the purpose is less to win than test the skills against non expexted and non trained situations.
As I mentioned in the discussion yesterday, both fighters tend to fight according to their tournament rule set, which naturally to the safety of the combatants, includes forbidden moves.
So the common "brute" argument is "with real weapons it would like ...". Well as nobody really wants to test that out with real swords there is still an other option to "see" if one combatant is superior to the other, which in the end still says nothing about the superiority of the different styles: paint and colored markers on white clothes/armor.
An example of how it this works, is using text markers/high lighters eg. in a knife defense/offense training. Each cut leaves a marking on your arms and cloths and you can very easily see that if you ever get into a fight and sobody draws a knife that it's much wiser to run rather than stay and fight. As one trainer during a knife defense workship once said, knife defense is not to learn not to get cut but to be able to decided where you get cut.
Looking further zukurus other videos are also very interesting:
