When and where?
Even accepting those at face value, they hype up the SoSP and Uchiha clan more than their eyes.You must be registered for see imagesSharingan 写輪眼
This is konoha's finest clan, Uchiha Clan's bloodline limit. Within the clan, there is only a portion of the members, possess this special ability. The tomoe seal within the pupil is the special markings of the Sharingan. Sharingan is an observation eye, which is capable of exposing everything, an illusion eye capable of casting illusions and also an eye of jutsu copying capabilities. Just like in the battle between Kakashi and Zabuza, where it seems like it can predict the future, and using different combat methods, allowing the user to have unlimited defensive and offensive strategies.
Sharingan's observation eye, is one of the finest in doujutsu. Within split seconds, this observation eye is capable of exposing to the user all systems of Ninjutsu, Taijutsu and Genjutsu, also the movement and attacking path of the opponent, or the opponent's defences against fatal moves, evading movements from the user's attack, etc... These will enhance the overall combat abilities of the user in different situations. This petrifying ability is worthy of the title, "Heaven's Eye".
Plus the ability of copying, Sharingan, can wield its true capabilities... that is to copy and possess jutsus seen only once by the user. Regardless of whether its chakra molding or seals forming, all the under lying physics of the jutsu will be copied and remembered by the user in an instant. In order to weild the jutsu, the user must have sufficient chakra and also an able body that can withstand the demands of the jutsu. However, an Uchiha will not allow himself to be restricted by these conditions. This is because they will utilised their accumulated combat experience, and also bring out their potential when the need arises. The more critical the situation is, the more they are able to harness their potential to the maximum.
Byakugan can see complete energy pathways while Rinnegan only sees energy colours.byakogan couldn't rezizt to mugen skoyomi but rinnegan did..
Strictly speakingByakugan has no Genjutsu of any kind, which makes it automatically fall behind Sharingan in that category. Offensive power; The Mangekyou gives the user access to jutsu like Susanoo and Amaterasu, as well as extremely powerful Genjutsu such as Kotoamatsukami. The only category in which Byakugan is slightly better than Sharingan is physical combat. It allows the user access to Gentle Fist and targeting chakra points, but still Sharingan allows the user to process and move faster than the enemy. The Sharingan's jutsu can also be used at a distance, meanwhile Byakugan users have to get into close combat to use Gentle Fist or other types of Byakugan related jutsu, making Sharingan and Rinnegan with it, superior to Byakugan.
