While they may have "better" powers, I really don't think Poseidon or Hades's children are more powerful than Zeus's. Yeah, Poseidon is all about water, and Hades is all about death, so the kids make the most out of those powers.

But Zeus's main feature is being THE KING OF THE GODS. So his kids, even though they have the least amount of powers, are probably able to use their abilities in the best, strongest, and most powerful ways. Also, as descendants of the KING OF THE GODS, they probably have the greatest overall strength and leadership qualities- including Perseus, Hercules, Achilles, Thalia, and now Jason. No, they don't have a large quantity of powers. But they are pretty damn powerful!

Does that make sense?
