Minato (the 4th)...space/time jutsu is crazy, plus he's considered the strongest hokage for a reason
kakashi...smart, dependable, has sharingan
jaraiya...other then being really powerful and having alot of in battle exper. the jutsu he using in the manga
against pein is wow (even tho he dies
)
naruto...kyuubi, very inspiring, never gives up plus has the greatest stamina and possibly the greatest chakra ever (not even counting the kyuubi's), oh and gets stronger with every battle
tsunade...very strong, focused, and a medical genius
(if i could chose 6 then Sarutobi would be next on the list and if we had a top 10 shikamaru, neji, lee, and Zabuza would be next)
