Honestly due to recent events in the series it was impossible for 2nd and 1st to be at 100%. Orochimaru had 100% control over them so it would have been impossible for them to be at full strength.
Main and only reason I really need to explain is that the 2nd (and im sure orochimaru) knew about cancelling your own contract with edo tensei and to prevent the 1st or 2nd from using it orochimaru kept them as mindless puppets. Thus preventing them from turning on him
So to conclude the kage brawl its fair to say NONE of them them were at there full capability
