True, but logic would dictate that a direct slash would conserve more energy. The more energy transfers that are done, the more energy that is lost in between each step.
Look carefully at that scan.... the 8 tails also had a tentacle blown off....and it's main torso wasn't damaged either....
B left that tentacle behind, he never took on the Juubi laser, ever. The only one who did was Naruto. That leg is there because either B left it there or Kakashi cut it off as

Defense
Greater blue-ringed octopus (Hapalochlaena lunulata)
An octopus's main (primary) defense is to hide, either not to be seen at all, or through camouflage and mimicry not to be detected as an octopus.[18] Octopuses have several secondary defenses (defenses they use once they have been seen by a predator). The most common secondary defense is fast escape. Other defenses include distraction with the use of ink sacs and autotomising limbs.
Most octopuses can eject a thick, blackish ink in a large cloud to aid in escaping from predators. The main coloring agent of the ink is melanin, which is the same chemical that gives humans their hair and skin color. This ink cloud is thought to reduce the efficiency of olfactory organs, which would aid an octopus's evasion from predators that employ smell for hunting, such as sharks. Ink clouds of some species might serve as pseudo-morphs, or decoys that the predator attacks instead.[19]
'Autotomy ' (from the Greek auto = "self-" and tomy = "severing") or self amputation is the behavior whereby an animal severs one or more of its own appendages,[1] usually as a self-defense mechanism to elude a predator's grasp or to distract the predator and thereby allow escape. The lost body part may be regenerated later.
Sigh....I'm in no way stating that, please don't put words into my mouth. Full Kurama's Bijuudama outputs significantly more energy, no where do I deny that.
For Enton Blade to be able to damage Perfect Susanoo, it'd have to do
much much more damage than Full Kurama's Bijuu Dama as the latter was tanked with absolutely no damage hence it being on another level of power. So yes, you did state that whether you realize it or not. If they are in the same power range or weaker than obviously it won't do any damage.
When I say this I'm talking about the damage done, nothing else.
What I'm saying is how that energy is applied to the opponent. The 8 tails had a tail blown off from both the shuriken and the Juubi's laser. In the latter case, the 8 tail's torso wasn't damaged, so the Juubi's attack didn't simply go through the tails like butter. This showcases that cutting attacks apply a greater force that is many order of magnitudes greater at any specific point than explosive attacks.
Woah, what are you talking about? Hachibi never took on the Juubi laser, Naruto took it on alone. The Tentacle is the result of Killer B leaving it behind, same thing he did against Sasuke or it was Kakashi, I'm not really sure though, but I know the Juubi's laser didn't hit it. I hope you don't think that the Juubi laser cut that tentacle off when its not even a cutting attack in the first place and the tentacle wasn't even damaged in the slightest.
Will an Enton blade cut through a Perfect Susanoo for sure? We won't know until (if) Sasuke fights Madara. That's not the point of my post(s). I'm stating that there are feats to suggest that it's a possibility considering the amount of force applied to a specific point by a cutting attack, versus an explosive one.
The only feat you have is pretty much invalid.
