Hercules is supposed to be physically stronger than Thor by a small degree. Rune King Thor and this version of Herc are both on Skyfather level except that Chaos War Hercules is stated to be the most powerful skyfather ever to exist.
Both are far above Skyfather level. RKT is around multi-galaxy level. CWH is close to multiversal level.
I wouldn't say they are far above skyfather level, but they are above them.
