No, he doesn't have superior reactions to Minato. He did some stuff while Minato was in denial trying to do his best given the situation. Tobirama was just more focused. That doesn't prove he has superior reactions. Minato was literally following Guy's 8th gate speed. That's beyond anything Tobirama has ever done.
Edo Tensei doesn't help against Minato thanks to teleportation and his sealing jutsu which can release the binding when someone controls you. Displacing Kunai can't stop Minato from teleporting too. Minato has Tobi beat in the area that matters the most in a fight b/w them.
He doesn't need any. He could beat Tobirama with a Kunai or Rasengan.
