As we know that oro could take hiruzen down in this war.
But, oro was much weaker as compared to itachi at that time.
Kisame, then, was still almost equally strong as he was against bee (he couldn't have earned tailed beast like status in those 3 years)
As for guy, i think he was capable of opening 7 gates if opportunity presented i.e. face to face match with any strong ninja. After all, even lee was capable of opening 5 gates.
So, guy could have beaten kisame even then too. And if he could beat kisame, then there could not have been any ninja stronger in konoha than him at that time.
I think I made myself clear.
