EEEEEEH, which one wins? I'm not all that interested in comparing fictional work in terms of popularity or power levels for fight scenes, truth be told
Seiya won with just the Bronze Cloth against Goku SSJ3. This the third time I saw people outside from the SS fandom who thinks that Seiya is OP. You have to look the analysis in the beginning and why Seiya won just for fun then tell me what you think, you don't have to look the fight, but see why Seiya won.
