Murata said he didn’t know who was stronger between Orochi and Golden sperm (webco) who is the new platinum sperm in the manga. But he said that Orochi has better fighting skills while PS/GS was just about speed and power.
So I think this imply they are close/really close power level wise but Orochi has a little edge
So I guess Orochi => PS. But they are in the same realm of power
