Lore wise if the Necrons ever fully awaken they would be the strongest hands down. The only reason anyone can stop them is because they are malfunctioning, and are awakening earlier than they are supposed to. The other contender would be the Tyranids. They were designed by the old ones to cleanse that sector of the galaxy and out number literally every other race. If the God-Emperor were still a factor and humanity had secured the web-way they would be the dominant force, but because of the Horus heresy both them and the forces of Chaos are on a slow but inevitable downward spiral unless (insert dues-ex machina/ plot device here.) The Eldar are already doomed, and the Orks while resilient would be overtaken by the sheer numbers of the Tyranids, and the mechanical efficiency of the Necrons.
