The three most powerful factions are the c'tan, old ones and tyranids. The c'tan are mostly split up and enslaved by the necrons, the old ones have been gone for tens of millions of years, and the tyranids have just arrived from outside the galaxy (giving them the auspicious achievement of being one of the few races from outside the milk way).

At the moment there's no question that the tyranids are by far the most powerful. Should the c'tan awaken or the void dragon be released, they will rival the tyranids, and should the old ones return they will be the strongest.

The imperium or orks are extremely weak in comparrison...
