Debate 2: Sharingan/Byakugan(Continued)
I want to state that really seeing the chakra network and tanketsu points is the only really relevant advantage that the Byakugan has over the Sharingan as far as seeing chakra goes and thats because of the gentle fist.
Now while Itachi is a master of genjutsu and whatnot the Sharingan can copy any non kekkei genkai technique so the genjutsu itself is easily learnable for the Sharingan and anyone who wields it so Itachi being a master is moot. Also it's unwise to take your eyes off your opponent during a fight it most likely will get you killed.
If kekkei genkai's are not secret then why do the Hyuga's brand their branch members with the cursed seal. I believe it was said to keep other ninja's from getting the secrets of the Byakugan. So, Kekkei genkai's are secrets that are hidden but of course information is gonna be leaked.
So, now to the subjects of countering the Sharingan. The form that Might guy used was as you said specialized and unfortunately impossible to pull off if you don't train with the form alot as Kurenai and/or Asuma said. So, that is once again ineffective and another thing to point out is that it only stops eye contact it doesn't prevent any types of jutsu's from being used.
Another thing is how does might guy being able to avoid eye contact with a sharingan prove that speed can win against a three tomoe sharingan user especially when we haven't really seen Kakashi and Might guy fight. I also have never seen taijutsu work on a 3 tomoe sharingan user unless were talking about Killer bee or E in which case your talking about a Kage that has speed similar to the fourth hokage and the 8 tailed jinchuriki. You'd have to fight at a ridiculous speed to keep the Sharingan from seeing your movements actually you'd have to move in from place to place faster than an instant.
Also back to the subject of Rock lee vs Sasuke. You can't say that it would have "assuredly" ended the fight because you don't know that. Now Gaara did have to use sand to soften the floor. But you can't know exactly what would have happened who's to say Sasuke wouldn't have slipped out. Additionally had Sasuke had his third tomoe who's to say he would have gotten caught with the technique in the first place. Also to think that Sasuke wouldn't have seen a weakness in a technique he copied is an underestimation on the ninja not the eye and the idea that the Gentle fist would hit in the first place is very much so laughable when I know your every move before you even make it. Your also thinking this is in battle and by your logic an Uchiha would know of the Gentle fist and the Byakugan and should be able to strategize against it.
Now as far the Heavenly Spin goes well I got nothing on that but it doesn't really matter whether you can block my techniques if you can't hit me either. Also your speaking of an advanced technique one that I've never seen anybody but Neji and Hizashi use. So, that doesn't account for an average user.
Now it's obvious that the branch members are the majority of the Hyuga clan. Now I took Hinata Hyuga who is by no means average and stated she can't use the best techs so why would random cannon fodder ninja z with byakugan be able to use it. Now as far as Sharingan users I was stating the point that while every Uchiha is brought up learning the fire style the Sharingan easily takes that limit off of it's user and allows them to copy their way into other elements. On another note Kakashi and Danzo have to count seeing as they are users of the Sharingan and we are talking about the Sharingan and not the Uchiha's only by extension do we need to mention the clan. But in all we are talking about the possibilities the Sharingan opens up to the user.
Now what time a ninja manifest's the Sharingan is partially up to the user and partially up to chance of a moment of emotional duress. But the Uchiha are ninja's and ninja's go on dangerous missions and more than likely one of those missions are gonna be dangerous enough to put the Uchiha at hand in a stressful enough situation that the Sharingan activates. So, although times may vary it's hardly a problem for an Uchiha to activate his Sharingan when he's thrown into stressful situations often. While on that note I want to make it understood that it takes very little skill or experience to use the Sharingan seeing as everyone we have seen get it has absolutely no issue in it's use.
Now onto team battles. Now the Sharingan takes note of all things in it's range of vision so for you to imply the Sharingan becomes negligible in combat against a team doesn't is partially untrue and it goes against the fact that the Sharingan is a supplementary doujutsu it's advantages are very much so based on the user and what the user has acquired with it. So, even when the Sharingan isn't in use it still plays a role in combat due to copied jutsu and techniques. Also it's very effective even against a team due once again to being able to instantly trap one in genjutsu and to be able to predict the move of the others in it's field of vision. Now a team going against a byakugan user is very much so different simply because even though a Byakugan user is receiving the visual information doesn't mean his eyes can process it all which is why Kakashi needed Sharingan to perfect Chidori. It was because his normal vision couldn't process all of the information so he couldn't prepare for the inevitable counter attack and since the Byakugan doesn't enhance the vision it increases the range and provides telescopic vision it's susceptible to the same issue. So, it's effectiveness is the one that goes down against a group.
Now as far as scouting goes and most other things the details matter and the Sharingan pulls out the details. Which is why it can very well be effective in the scouting situation while the byakugan does not so it can miss something. It can easily overlook a detail that might be the most important one.
So, maybe in your fantasy world the Byakugan is a better tool. But in here the Sharingan is the strongest doujutsu.
