I think your thread is pointless.
A. Yeah Naruto WAS meant to become the strongest, duh...
B. Hashirama obviously wasn't meant to be the strongest hokage till some time after part 2 started...
C. Whether anyone thinks Hashirama is over-powered or not is an opinion based thesis. It is not up to you or me to decide. I personally think the size of his wannabe budha statue, was too much, however, stuff like that aren't determined by its looks, so we will have to wait for next chapter to see the conclusion.
