Real talk:
I actually think P5's MC actually is the best. From the style, to the attitude, to how he handles himself with the situations that he ends up with, it's just fun to witness.
P3 and P4 were more in line with the silent protagonist blank slate. P3 was the Messiah that tired to save the world from harsh combat that came at him, P4 was a similar situation.
P5 everyone went looking for trouble, originally to inspire hope, and not just save the world behind the scenes.
Also, it's a fly coat.
