IMO, In decending order
- 5. Jiraya- Infiltrated mist vilage and had spied on akatsuki.
- 4. Itachi- Assanated his clan through the dead of night.
- 3. Tobi- Same reason plus the previous Konoha infiltration on naruto's birth
- 2. Zetsu- Akatsukis intelegence and has spied countless times without detection
- 1. Muu- For his moniker as a Non person
