Sage Naruto is very good. His clone is decently durable as well. And if the clone manages to survive, you got an easy chase starter. His damage is also somewhat high.

Overall, a very good ninja. Probably the best from the Sage Treasure (Although I don't know about Sasori)
Combine Sage Naruto with Sage Jiraiya, and you got a team with consistently high Chakra each round. These two work amazingly well together.
