He's fought Rinnegan before, several Mangekyou users (including Sasuke), Byakugan users, and uses Sage Mode himself and is a Jinchuriki. He was basically familiar with everything Kaguya could throw at him. Sasuke never fought the Byakugan. His experience against the Rinnegan consisted of Obito (Mainly surpressed Biju) and Madara (special technique spam). His experience against Sage Mode was a brief Naruto encounter. His experience against Jinchuriki is limited (Naruto, Bee). Naruto's power up was in line with his existing abilities.

It's not really clear to me what Naruto's limit of power is now, but surely his experience as a Hokage brought him some much-needed experience right? So i'm inclined to say that while his highest level of power is in the Final Valley, his Hokage is his prime.
