Most useful clan to a village

[Wood Style Tenzo]

OUT OF THESE:

Tracking, course-making ninja hound family. Super fast and big destructive style.

Strategy-making & intelligence with sneak attack jutsu

City-protecting size able to defend village from enemies even as big as Bijuu and Gedo Mazu

Chakra-draining, info-gathering bugs.

Telepathic communicators & Mind controller/destroyers (Yamanaka)

 

[Bimbonium]

They're all pretty useful, also, we don't know if the Nara clan is super smart or it's just Shikamaru's family.

Either Yamanaka or Akimichi for me.

 

[Joon]

They're all useful.

 

[Bad Touch Yakushi]

Nara and Aburame are the best all-rounders.

But Yamanaka are the most indispensable in a war scenario or a village attack.

 

[Genocide]

nara or yamanaka

 

[Darth AniCetuS]

Nara clan.
Apart from being great tacticians, they could also contribute to governing the village and create and implement good policies benefiting the village in every aspect.

 

[Pyro NB]

Torn between Nara and Yamanaka

 

[JaphethCrenshaw]

Nara is the best choice.

 

[HyuugaHeir]

Yamanaka, their mind based techs are indispensable. Recon clans follow.

 

[Hakke]

I would say Nara
