Arguing on behalf of SM Naruto? Fine, let's switch over to that field of battle.
Here is the Preta Path

Naruto's Senjutsu Chakra. See? Fine. Now, let's see what happens when naruto draws upon even more

And, after reviewing the
Nagato vs Itachi, Killer Bee, and KCM Naruto fight, I realized that the Preta Path technically has a greater chakra absorption feat. Samehada brought Killer Bee down to a V1 state. The Preta Path power just

all of it.
From this, we can rightfully see that the Preta path> Samehada when it comes to chakra absorption. Why do I bring this up? Refer to the earlier scans please. It wasn't until Naruto began feeding even more Nature chakra the Preta Path did it turn. After absorbing all of the Senjutsu Chakra, it was fine. Samehada will fair the same way, only it may or may not get it all in a single swipe.
Continuing from this; Naruto was still and capable of gathering the needed nature chakra. Kisame won't be holding Naruto down when they fight, it will be a quick thing. Naruto won't be able to defeat Samehada the same way He defeated the Preta Path.
Next point I would like to make, you are turned into a statue when you are overloaded with Nature Chakra. That's not death, and not for Kisame. And, let's assume Samehada HAS been defeated. Kisame still has high level ninjutsu he can use to defeat a chakra-lessened Naruto. He can summon Sharks, use a Suiton-Shark technique on various levels.
Hell, he could manage to trap Naruto in a water prison and drowned him with the help from his water clone jutsu.
You are right, highten'd senses will give Naruto a boost. But, Samehada does have a certain range to it's absorption. I've shown in an earlier scan with both Killer Bee's second raiton Sword(?) and the center-most part of Itachi's katon.
Naruto, if he does avoid a direct hit, will still be the victim of having some chakra stolen.
And a Water Dome along with a few water clones and water-formed sharks an potentially drown Naruto. The clones and sharks can keep Naruto away from the surface, and Kisame can keep moving in the general direction of Naruto to also make sure he doesn't escape.
Shall I bring up the Great Shark Bomb? Something that would effortlessly absorb Senjutsu chakra, in a worst case scenario. And I doubt Naruto will be avoiding something of

Not only could the water-formed shark bite down and do damage to Naruto that way, but his Sage Mode chakra would be gone and he would be in the middle of Kisame's jutsu.
I would say Kisame wins this more often then not, high diff.
Edit: As for your last picture post, that's what I meant by "Naruto's speed in KCM is Kisame's biggest issue".
