I'm kinda torn. Sabretooth is vastly superior to Wolverine. Creed only loses to Wolverine (when he does actually lose) because of CIS. Creed fights Wolverine because he likes to fight Wolverine, he gets a kick out of it of messing with him, and as such he never really takes it seriously. It's just a game to him. Now its possible Sabretooth would handle Daken the same way he does deals with Wolverine, fighting him with a grin on is face for shits and giggles to elevate his boredom... but I think its more likely that he would realize that killing Daken would really piss Wolverine off and go %100 full boar and tear shit up, which isn't something we've seen very often.
Pheromones + Muramasa might be enough to balance the scales, but I'm not sure. I still see Creed ripping Daken's arms off. 🙁
