While it surely gives quite the reflexes, Sage Mode alone doesn't make you fast enough to dodge the Raikage. Naruto already learned superior Shunshin by then via KCM, even before that against Pain he had already used Kurama's chakra to superpower himself. We've seen before that Naruto's ability to use chakra increased with his connection to Kurama.

Again: How powerful this is depends heavily on the user. Byakugan itself needs a lot of practice to use things like Gentle Fist, whereas Sage Mode only unlocks it's true potential by utilizing it with other skills. A good Byakugan user will defeat a bad sage and vice versa.
