Considering the power at which Hokage fight, it may simply be that they mastered low-level jutsu that aren't of sufficient power in a Kage fight. he had more than flying raijin plus rasengan he had a flying raijin plus body flicker plus rasengan combo he used all three when fighting thats why he was so fast(because he used the flying thunder god for teleportation but used body flicker for high speed attacks and to generate kinetic energy for the attack
