The correct answer is that each case resulted in the Federal government getting more power, in one way or another.
In Marbury v. Madison, the Judicial Branch elbowed its way into establishing the ability to review laws to determine their constitutionality.
In McCulloch v. Maryland, Congress got more power when the Supreme Court ruled that it had implied powers.
In Gibbons v. Ogden, the Supreme Court ruled that states can't get in the way of Congress acting in their role of arbiter of interstate commerce.
