naruto wins this,
bunta help him close the distance and combat deidara if he manages to get airborne, and with that starting distance, naruto can shunshin to deidara and slam a rasengan at him
As fast as FRS is Pain was able to avoid that shit on the ground.... Also are the toad sages there? As all three of the summons may be a little annoying for Deidara but one can be taken care of.
Naruto will probably try to launch himself with clones and when he does Deidara can merely either jump off the bird and make a new one to land swiftly (while exploding the other of course) however he was shown to react to Hebi Sasuke's ambush attack.
Wait..this SM has enhanced durability doesn't it? Deidara would need to ambush him via clay clone or C2 created dragon in the sky.
Naruto wins mid-high diff. Ma summons all the boss toads and they give Naruto an opening to FRS or Rasengan his ass. Snakes can't jump so Sasuke had it harder.
