Why would he underestimate his durability? he knew his rasengan hit obito's shoulder earlier and it barely did anything other than tear his clothes, give him a bruise, and sent him flying. He says "who are you" before breaking his mask as well, indicating he wanted to know. Naruto isn't stupid, I'm pretty sure that was just plot. Rasengan is enough to give Obito trouble but I highly doubt naruto would think that would be the optimal choice for an actual kill shot, given what he knew about obito's durability.
