What a fail post. Partially blind=you can see a bit, meaning he still has sight. Blind=No sight at all.Unless its edo bm minato, Itachi takes this rather easily.
To state the obvious first.
Minato cannot use no ninjutsu without his arms, including hiraishin.
Apart from not being able to throw his kunai's, hiraishin requires so much concentration that numerous times we have seen minato forming the seal of confrontation.
I keep hearing gai would go 7 gate and blitz. What is he blitzing with no legs, his upper body?. Unless gai can fly, blitzing with his lower body will cause him more harm than good.
Itachi wins simple because firstly, itachi has for a number of years been partially blind therefore blindness is no issue to him, though in this case its total blindness.
Secondly he has his 4 other senses most importantly, most importantly hearing and smell.
He was the captain of the assassination squad, so while not saying he rivals zabuza at silent killing without any form of vision, he should be skilled at the very least to have heightened senses, excluding his vision. You cannot be an assassin which by definition should be somebody who is a master of stealth and tracking let alone the captain of the whole squad if all you depend on is your eyesight

He has shown us this on numerous occasions. Examples are his shuriken feats

OP you said itachi doesn't have his sight. However you never said his crow summons are also affect by this. SO itachi using his summonings can further guide him as his crows will have vision and will communicate/notify him. His crows will basically act like his eyes. So apart from his other heightened sense which comes with being an assassin, he also gains some form of vision.
He can use genjutsu without his eyes.
He has katon variations and suiton, along with either kage bunshin or karasu bunshins.
Itachi stomps!!!
He has no feats of being a sensor, so saying he can spot someone who is unexperienced in the art of stealth isn't a feat. Him being an assassin does no mean he can sense as well as you are making him sense (to fight with no sight). Again unless you show me a scan of all assassins in Naruto being sensors, than your point is invalid. Moreover, his crows have never communicated with him, unless you can show me scans of clear communication with the two. 'His crows are his eyes' lmao, sure.. when he can't even communicate with them. His finger genjutsu still requires knowing where his opponent is.. so your point of them being caught in it is a 1/100 chance. As to who I think would win, I say Minto easily. He can still use shunshin since he has his feat. None of them will react, to this speed blind sighted or legless. Minato can also drop hirashin Kunai's on the floor without using his hands, incase he feels the need for it. I am also assuming this is excluding BM Minato, or atleast hoping.
