Minato has more battle $wagger but Naruto is a more developed character.
For me, personality wise:
Part 1 Naruto > Minato
Minato > Part 2 Naruto
Mianto...fluck that Naruto fapboy character...trying to be like Mianto and Itachi.
Spam one or two jutsu that aren't even cool. Well wouldn't make sense to call FTG spam since its just move basically.
Here's one definition of spam I found:
spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam spam
This tells us that spam is just repeatedly using the same thing, which Minato is doing, therefore, Minato spams FTG.
