Not to mention a computer decides the winner lol..... Then what about the man them selfves? That counts more than what style, or weapons getting used IMO. Just like in MMA 
It's not so much a computer that decides the winner, the way the calculate it is like this:
they give each set of warriors ratings on the let's say physical stature, strength, armor , intelligence, resources (are they close to food,etc.) and tabulate the variables into a matrix, then they factor in each warrior's set of weapons which is see on the show, each one gets a rating (most likely out of 10) with me so far?
Then at the end they have a complete data set for A) the physical warrior B) his environment and resources
and C) his weapons and how well they performed. With probably a few random variable sets thrown in there like 'heart' , 'charisma' , 'agression' etc.
then each side gets their numbers tabulated and all the variables add up to the confrontation , which they do 1000's for accurate unbiased results. And there you have it
56 out of 100 times an indian could win with a bow and arrow and tomahawk against a pirate with a sword and pistol, at the end of the run they take the average out of 1000 simulations and declare the winner and how it most likely went down according to the computer (ie. if that exact same fight had taken place 1000 times)
