Even with speed equalized, sharingan gives higher reaction time as one of its key traits, so he wins speed and reaction regardless. And yes he can precog because sharingan sees energy including magic(saw deidara's c4 and verse equalization.) so he'd see in every way everything he does and how he's forming his magic JUST LIKE he's done against people before. Where and when did gray ever go through a whole fight planning things through? Sure, he adapts well but no... because he's tried twice now to kill himself with iced shell without thinking of everything or succeeding AND his last half dozen fights in manga have all been rage fest or go head first. Sasuke planned entire fights and outthought danzo and deidara while taking Itachi by surprise at least. Also, amaterasu to date has no been put out by anything other than the users will, even threatening and injuring the ten tails which can destroy the moon, so no, gray does not have the ability to freeze it OR put it out. Yes, barriers can block it but Inferno flame control, can remotely control the flames even after being blocked. Yes, gray has durability, hes also only got one startup to any move since all his ice make starts the same, and this gray doesn't have anything that lets him use it faster like devil Slayer or his more recent boosts against the spriggan. Also Sasuke loses in stamina but keep in mind he fought not one, but two kage level opponents and survived the attacks of three more and showed he would have killed at least Ay, and his eyes still held enough to go the whole danzo fight and THEN fight Naruto. His eyes aren't going to go blind that fast. He loses stamina but not by much. (Yes I know he got a chakra recharge, but your main argument was the eyes and his chakra still let him survive multiple fights)
Sorry, the only thing you brought up that isn't countered is durability which lightning attacks Pierce through. If you're implying that ice make is more versatile than flame, amaterasu control, susanoo, chidori, chidori stream and sharpspear, move reading, snake summons, and hawk summons... Sorry, making a cage, gun, plugging a hole, or sending any number of objects that do accomplish the same goal does not equal or exceed. Planning around Racer's limitations doesn't equal or exceed consistently outplanning multiple of deidara's moves on the fly and living each time. And gray I believe has only recently got to the point of putting out cold temperatures capable of arguing the amaterasu thing.
Still going Sasuke. Gray is awesome, but no. Durability is negated by most Sasukes moves so i think you're over estimating Gray's control of his emotions and intelligence to win.
