Well if we are basing this off of 2009 Jason, basically turning Jason Voorhees' creative mode off. Jason V still has a lot going for him, he seems to be a unit of a man, taking on multiple hits, and being able to deliver serious blows. Now Jason on the right here, from what lore I've gathered, seems to be a military operative of some sort. Depending on rank, he may have access to some very solid tech, a variety of long and close range weapons which could get the job done. However, lets also consider that both Jasons are being given even playing fields, neither are given any advantage, so lets say it's a close range blade fight. In this case, it comes down to who can tank/deal enough severe cuts to their opponent, my money leans towards Jason V, like I said he is a damn tank of a person from what I've seen. But I don't think this fight is one sided, Jason, if he uses some sort of strategic way of attacking, could bring down Jason V, probably from slowly cutting away at him, but it's not certain. It's interesting to think about.
