To be honest, i dont think its close at all. At least it doesnt seem that way. Ill say why.
WW simply overrired Iron Mans armor with high Electrical vltage. You'd think he has some sort of protection against it, but on many occasions has someone put him down by blasting him with a high electrical charge.
Black Adam's strength is on Superman level. I dont think Wonder Man can match that. Dont get me wrong, hes no slouch in the strength department, i just dont see him matching well against BA. Although Simon does have some pretty high durability along with flight. Its just not enough though.
Luthor with the battle suit may be able to take out Cage. If not, he can always get help from one of his free teammates. But considering that hes able to take hits from Superman, i doubt Cage or Spiderman can do much damage to it.
Deathsroke could beat Wolverine and SW alone imo.
I do think Cap is beating Talia though. Shes good, but just not on Cap Batman Slade level. Either way Cap gets outnumbered in the end.
