Let's compare a few aspects of both in order to determine once and for all who should remain as Wolvie's arch-enemy or if they should coexist as such.
He is driven mostly by power and revenge. His ultimate goal is total control of everything, and in order to achieve that he has mastered many manipulation techniques. He is indifferent to money and pleasure, as these two things he uses only as means to his ultimate goal: total control. He has the bestial nature that all feral mutants (ex. wolverine and sabretooth) have, but he is able to manage it in pro of his ends.
He is bisexual, which only means he is willing to compromise his sexuality in favor of his objectives. This makes him unique. Not even the most cold minded of master conspirators in the past have been willing to compromise their sexual preferences (I can't picture Helmut Zemo taking a hump from behind in order to achieve his goals).
The only other thing he holds sacred is the memory of his mother, which leads him to hate his father, who he blames for her death, and Bucky Barnes, who actually was the one who killed her during his time as the Winter Soldier. So that's why his other goal in life is revenge, mainly against Wolverine, who he wants to destroy with his own hands.
This will be written in present tense as if he was still alive.
Victor Creed is driven by a thirst for blood and guts. He lives for murder, cruelty and sadism. Apart from that, he hates Wolverine above anythig else, for reasons that have never been clearly disclosed. However he sometimes does random out of place stuff like spying and conspiracy which don't fit the character at all. Likewise, given all the hatred he has for Wolverine, he has never taken serious steps to end his life for good, which doesn't make sense.
Supposedly all the decades of rivalry and hatred between Wolverine and Creed were just one more part of Romulus's scheme, and Sabretooth was always nothing more than a mere pawn in it, and that's how one of Marvel's most important and longest rivalries has been explained.
My vote: Daken
2. Power and Strength:
Here, they seem evenly matched in regard to strength and fighting skills, as well as healing factor. However, Daken has the advantage that he can release some pheromones and he is able to manipulate others to do his will, so he wins by a slight bit.
My vote: Daken
In his civilian look, he looks like a metrosexual emo rock star. His newest costume is dull. He only looks decent in Wolvie’s old costume.
In his traditional yellow and brown costume, he looks silly, but as a civilian, he looks like a truck driver on steroids, with claws, fangs and other feral features. Thumbs up.
My vote: Sabretooth
