This is rather interesting since Jensen can have multiple builds, some for just raw power, others for stealth that will blow Fisher's skills out of the water. In either case, I think I have to give the edge to Adam Jensen.
If Adam Jensen was pre-augmentation (so just human), then the fight would go to Sam Fisher.
Oh, certainly. No contest there in my opinion. But since we pretty much really only get to interact with Jensen post-augmentation, I'm assuming that for the sake of the Rumble. And once he gets up there with the augments, he becomes either a beast, a shadow, or a mixture of the two. Fisher would get pasted.
Sam Fisher. Adam Jensen is insufferable
I voted for Gene because he's not Kratos. THE END.
I believe that this next round should be a draw -- both characters are only shells of themselves until they reach the end game. I elect not to vote in this round.
