Vaush is dishonest, and manipulative, but he knows how to work an audience and put the pressure on(he was even semi charming when he debated Tim pool, and did fairly well). Jason easily has him out theoried and out read, and he's generally alright at holding his position, although 3rd worldism has its issues which has disadvantaged him from time to time. I see Jason getting dunked on but mostly coming out on top. Vaush will use the same straw men as he used on Caleb, and his rhetoric can be nicely structured with various traps, but I'd still put my money on Jason, hes played this game enough to know how to handle people like vaush. 60% Jason, to 40% vaush margin.
