The Sabretooth given by the original poster (OP) of this thread shows a Sabretooth (Graydon Creed) whose healing factor was a fraction of the current one. That version of Sabretooth was strong and fast, but his highest feats probably place him at the level of a low tier version of Spider- Man.
He often fought with pure savagery and little thought, one because he was often overcome by rage episodes, and two because, presumably, the level of his average victim didn't require more than some thoughtless mauling on his part to overpower them and win.
For an opponent used to calmly battling the toughest big game wild animals, including tigers, enraged grizzly bears, and bull elephants, hand-to-hand, ferocity's not likely to cut it. Especially not when Kraven's most famous opponent, Spider-Man, officially scores well above Creed in both level of strength AND speed and agility.
Creed's high-end wins during this time are impressive, but they generally relied on him ambushing his quarry, not taking them in a fair direct confrontation.
In straight up fights of that sort, Creed not only has losses to Power Man, Iron Fist, and Wolverine, but also to Spider-Man (who simply webbed his face, and the rage of Sabretooth caused him to violently yank the webbing, and then state that the webs ripped his face off, and collapse in agony, needing hospitalization),
and then later to the Black Cat, Spider-Man's ex-girlfriend, bereft of her "bad luck" powers, who, suddenly terrified by Sabretooth biting and tearing her leg, and realizing she was saved from serious injury only by Sabretooth's surprise on finding metal there (her lock picks, part of her outfit due to her being a literal, reformed professional "cat" burglar), proceeded to charge, and then flip him, and then pound his face repeatedly into the concrete, until he was rendered unconscious.
Kraven would not need any fear-induced adrenaline rush to duplicate the force of Felicia Hardy in that episode, and, besides the aforementioned darts and alluded to poisons, Classic Kraven had one more weapon Creed would be unaware of which should prove decisive in a first encounter:
Note that the stun effect on Spider-Man, a metahuman with surprising resistance and recuperative powers of his own, was such that he was incapable of striking back until Kraven had not only dealt with him, but also captured Osborn from the street with coiled cable, and confronted Osborn on their past transactions, and found that Osborn had no memory whatsoever of such things, and let Osborn go and himself proceeded to depart, before the now-forgotten Spider-man was in shape enough to give chase.
I've seen little to indicate the Sabretooth given to us by the OP has what it takes to take Kraven in this proposed KMC match bar surprise or the standard chaos of battle.
Kraven 7/10.
