I got this from the Naruto wiki, what do you guys think?
Sasuke Uchiha
Even by the Uchiha standards, Sasuke has exceptionally strong and large amounts of chakra. At age 7, he was already able to use his clan's signature fire release technique. This later surprised even Kakashi, as such techniques usually require more developed chakra. In Part II, his reserves grew considerably greater, able to use many highly chakra-consuming techniques in a day, even recklessly using three different Mangekyō Sharingan techniques plus Chidori multiple times respectively without visible exhaustion; able to continue fighting effectively with plenty of stamina left against the Kage. Also, even when extremely weakened, he could summon Manda, a high level summon (though he may have used Orochimaru's chakra for this). After gaining Itachi's eyes, Sasuke's reserves appear to have grown even further, as during the battle against Kabuto, he was visibly unaffected from using several of his Mangekyō Sharingan techniques as well as his Chidori multiple times.
Quality-wise, Sasuke's chakra is very powerful; its strength is compared to that of Madara Uchiha's, whose chakra was particularly strong even amongst the Uchiha. When Sasuke first arrived at the Land of Sound and gave Kabuto a frightening glare, both he and Orochimaru noted Sasuke's exceptional chakra. His chakra's strength was even great enough to break free from Danzō's restraining seal by releasing it from his entire body. Likewise, his chakra control has also grown considerably. With many high-level techniques, usually lightning and fire-based, he can perform them with few to no hand seals, giving his opponents little time to react.
