Right now i use naruto sosp(not Only mystery,standard and passive is full sb) in 1st, 2nd po edo madara (almost full sb,i have him in +1 chase so hes just missing +2 chase), and 3rd position is edo kakuzu. and so far this team does great even with whales in arena and players who focus on using sosp naruto. it all depends on how you use madara and i use his +2 barrier so i can easily poison opponent if they do not break my barrier. before i got edo madara i used team with po1 naruto, po2 kisame and po3 akatsuki kakuzu and it did great well aswell but its hard to defeat sosp teams with it. so my sujjetion is go for edo madara and if possible sb him

sorry to comment i could not edit i made few mistakes, what i ment was i u se akatsuki kakuzu in 3rd place, not edo kakuzu and my naruto has full sb only on mystery, standard and passive
