between the uchiha clan and the hyuuga clan which clan is stronger and as the most advantage of surviving a battle between the two clans
The average Hyuuga is stronger than the average Uchiha. People fail to realize this.
Not every Uchiha can even awaken the Sharingan while every single member of the Hyuuga have their Byakuyan. They're also trained in, what Lee and Gai call, the strongest form of taijutsu in Konoha.
The Mangekyou Sharingan is a
rare occurance in the Uchiha. People have a habit of personifying this rarity as the entirety of the Uchiha Clan's strength.
Not every Uchiha are like Itachi, Shisui, or Sasuke. People need to face it.
This is how it works:
-The average Hyuuga is more powerful than the average Uchiha.
-The strongest Uchiha is more powerful than the strongest Hyuuga.
If we're talking about a generic clan-wide battle, then the Hyuuga take this.
