Now I jsut read gins profile, gotta say tough opponent as usual, like reppuzan says if he likes out his move Kens life will be over, however i think Ken wins on the ground that if Ken is actually bloodlusted he won't hesitate at all to immediately activate Museo tensei or use his aura to hit gin from a mile away without gin even realizing it.
For one thing, gin does not know about Kens deadly hax and their are techniques that hit pressure points regardless if you are blocking (tenha kassatsu and Raohs go no Ken) ken Main advantage in this fight is his incredible variety of hax and incredibly combat skill and precog, Kenshiro is very familiar with cellular level attacks, in fact he has tanked it before,
the one problem gin has to go up to touch Ken to use this move, that is a big no no, since one, Ken would most likely have finished him with any of his broken haxes like Hokuto Shinken, gento, and MT(he has used it on random fodder because he was actually very pissed.)
gins one good advantage (besides a strong hax) is his strength, and I dont think thats enough, considering Ken doesn't waste time on opponents and goes straight for the kill, especially when bloodlusted. I give this too Ken Mid difficulty becasue gins hax needs him to touch Ken which he won't(alithough if it has range this could pose a problem but when Ken see him glow and stuff, he'd most likely go into defensive and subconsciously use Amat for safety and precog helps to predict this as well.)
Ken has the more variety of hax he can use, and has several dozens of attacks with good range. And overalls I believe is the more skilled fighter. Gins intellect and strength will get him far, but I don't see him gaining the victory.
