Yeah it's almost like there are conflicting statements on this particular issue that cast doubt on that idea. Like how the director of the game says Old Kratos (who Baldur was a match for) EASILY beats Young Kratos (who beat Zeus twice). Or the novelization straight up stating Baldur is the strongest opponent he's ever fought. Ragnarok doesn't exactly help here since in that, Kratos notes directly that Thor's blows (not even counting the hammer) are as heavy as any he's ever felt. At the very least, I think it's safe to say top tier Aesir are PHYSICALLY superior to the Olympians, even if the Olympians have more going for them in terms of hax.
