Well, considering the Sharingan doesn't run on chakra points (save for the associated techniques) once it's activated, it's basically promoting an Uchiha reset over that of a Hyuuga.. They should be evened out...
We all know the Sharingan requires chakra to maintain, an example of it having to be deactivated being when Itachi fled from Jiraiya, and having used Amaterasu and previously Tsyukuyomi, he was forced to deactivate it, an action he rarely performed due to his mastery over the Dojutsu (Kakashi doesn't count, seeing the strain of using the Sharingan is massive on a non-Uchiha).
