.Alright. Before Luffy looks bad, I'll intervene.
Shadow Clones
Luffy will sense the real clone without hesitation.
Luffy was able to s
ense Mr. 3's Wax Clones that were
perfectly identical to him
just via instinct.
Using Neji as a counter doesn't mean anything. Neji doesn't sense via instinct, he senses via people's chakra reserves.
Naruto's clones don't think "I'm the real one, I'll fight him him", they think "I'm a clone, I'll work as a diversion", and Luffy's telepathy will note that and ignore them.
Even without color, they were
complex enough to fool intelligent animals.
Luffy can
fly. Shadow Clones cannot fly. That is not an argument.
Sensing
Naruto has extra large range, enhanced senses, presence sensing, and has danger sensing.
Luffy has true precognition, telepathy, enhanced senses, intent sensing, danger sensing, emotional sensing, and presence sensing.
Luffy's precognition can counter someone else's precognition
Luffy badly out senses. This is not an argument.
Durability Negation
Luffy has taken far more internal attacks than Naruto.
Impact Dial, Rokuogan, Fishmen Karate, Haoshoken, and more.
Naruto has taken Gentle Fist, and that's it. And Gentle Fist doesn't even work like good internal damage, it works via chain reactions and such.
Frog Kata works exactly like Fishmen Karate. Frog Kata sends chakra into the body, Fishmen Karate sends Water and Shockwaves into the body. No difference, and Luffy in base could take that.
Luffy could power down and use a Red Goken attack (double durability negation) on Naruto, and Naruto has nothing to do against that.
Conqueror's Haki
Conqueror's Haki is
useless. Stop arguing Conqueror's Haki, it doesn't do anything to someone of Naruto's willpower.
Rasenshuriken
Luffy has Advanced Busoshoku which has attack redirection which could partially redirect attacks from a 6-B character. Until Naruto's Rasenshuriken is 6-B, that's wraps.
Time Limit
Naruto can only use Sage Mode for
like 5 minutes. With another clone, that's 10 minutes. Naruto stated that he needed to practice how to maintain it longer, but he hasn't shown how much longer he can/has extended it.
Luffy can fight for hours in Gear Fourth. Luffy out staminas.
Attack Potency
Naruto has higher attack potency.
Speed
Speed is Equalized.
Verdict
Luffy outstaminas, better sensing, tanks durability negation, redirects stronger attacks, more maneuverable, and so on.
