Didn't we do this thread in the manga section? Anyhow, since Kabuto is out because he is CLEARLY not genin material, and Shikamaru is out for being a chuunin and all, the best team is:

Naruto: offensive raw power
Gaara: unbeatable defense
Neji: Information gathering and well rounded fighter.

If they need a leader, its Shikamaru, he would probably know better than anyone how to use their talents to the fullest. Why use a jounin when a chuunin will do the job?
