Did gay marriage proponents actually win anything substantial?

The Supreme Court's decision on gay-marriage finally came out yesterday. The biggest decision was the justices decision about gay marriage. It essentially boils down to this: In states that allow gay marriage, gay couples qualify for federal benefits. So if a gay couple lives in a state that already defines marriage as between a man and a woman, they will not qualify for federal benefits. Essentially, states rights wins. Well, for now.
