Hashirama and Tobirama are Senju, the only ones of their clan to actually inherit the powers of their ancestor, Asura. Kakashi had his Sharingan copy just about every single jutsu he's ever seen. Naruto was given the power of the Sage of the Six Paths. So from what I can tell, the only one that actually managed to master the five styles naturally is Hiruzen. And both are feats, because they've been given these titles for a reason.
