If you're thinking about using the Therian Forme in doubles, then know this: Sand Force boosted Rock Slides and Earthquakes will always be more powerful than those coming from Landorus-T. Landorus-T is, however, the superior choice if you are not using a summoner of sandstorm on your team.
In fact, he makes a great anti-sand Pokemon b/c of Intimidate, immunity to ground, and EQ for Rock and Steel types.
