One does not compare a single faction when the entire Tyranid race is in question, the Imperium would be defeated within weeks if all the Tyranids came, the only way for them to be defeated would be for the entire galaxy to ally. (Atleast the forces of Order anyway) and even at that, a Tau, Eldar, and Imperial alliance still might not be enough. But on the otherhand, if the Necrons manage to awake more of their kind, and even awaken the Void Dragon, the Imperium is doomed for certain seeing as the Necrons are capable of the worst.
