Unless you're talking about strength, it's a matter of opinion.
Strengthwise, Madara.
no maybe because he has the six paths of pain and madara is by his self so pain will probaly win
Madara of course.I mean like he can manipulate the nine tails .All pain can do is stab you with chacra receivers.
Akatsuki was created by Madara Uchiha. So, pain's killing doesn't affect it much since madara is still alive.
Madara Uchiha is a man.
no but later in the series after nagato (pain) dies he takes it
Pain was the former leader but now the leader is Madara.
They are still sealed away. Madara has acces to them.
the leader of the akatski is Tobi Tobi, is the name used by the leader of akatsuki but his real name is Uchiha Madara.
Pain is the acting leader of Akatsuki and he's taking order from Madara
no it is rumered that Tobi is madara uchiha in obito's body but no pein is not obito
Konan did, as did Jiraiya.
At first it's Pain but Naruto kills him and then it becomes Madara Uchiha(Tobi)
