Rofl is this a joke? You make a list by feats shown in the manga, and yet you take EMS Sasuke, and say, you ned to see more from him. Wtf is this. Itachi has proven more potential than Sasuke, if he is fully fit, clear vision, no illness, from what is seen, you would put him in top 5 instead.
Also is it Nagato, or Pain? Cause that is of huge importance, and Pain is a lot stronger than just Nagato. Dividing his abilities among a number of shinobi, shared vision, etc. Nagato alone, doesn't make top 5 IMO. We haven't seen anything from him, except when he summoned gedo Mazou to fight, and when he was edo tensei, which means nothing. So we haven't seen Nagato fight, actually, so again you either forgot to mention the paths, or you are again going against your initial premise for the list.
And Minato and 3rd raikage has shown too little feats as well. 3rd raikage has shown no feats, and is all hype. You can't judge a person in edo tensei. Onoki, Gai or Kakashi, however, have shown enough.
