Actually Thor went into warrior madness mode for his fight against Maestro ( which IIRC wasn't actually Maestro but Prof Hulk posing as Maestro )
It should be noted that Thor's powers were screwed up in his own title during this time . But he apparently magically got his powers back right before the fight
Also in Thor 385, despite all the context noted , Hulk well ....came off looking clearly stronger by the end of it
As for Warrior Madness Thor feats , when he went on his rampage in Blood and Thunder , he was thought to be in Warrior Madness mode ( ultimately revealed to be not ). Sooo....maybe that's an indication of his power levels in that mode ?
As for Namor, his best feat is going toe to toe with the Hulk on land , multiple times on land, notably in Defenders 52.He also KOd the Hulk in a desert although he had multiple Avengers helping him, he was the one to deliver the knockout blow
