First off, the Winchesters aren't above everything else. Heck, even the Amazons are physical stronger than them. I haven't the faintest idea how you could possibly come to that conclusion. DEFINITELY not God, and CERTAINLY not Death. They have, however, gained the upper hand against higher beings, like demons, and with more difficulty Angels, and even Archangels. But, by resources, and NOT by physical capabilities.

In terms of strength, I think the first beasts--the Leviathans--possess physical, raw strength that exceeds that of ANY other creature except the Archangels, obviously. Oh, and and the Horsemen, because they in and of themselves possess no constrained form, giving them almost limitless strength.
