Cylons, hands down.

1.) Reserves, shitloads of them. Even if you exclude the whole "Centurion army" thing, you still have the humanoids who can infiltrate the Imperium. And if that's not enough, all of that has happened before and will happen again.

2.) Ressurection is a definite plus, considering as how the Zerg and Tyranids can't bring back their creatures from the dead with specialized ships. Or that their creatures can think for themselves.

3.) Sure, the Raiders aren't that special compared to a gunboat, but they're alive. There's also lots of them and they can become quite angry after multiple revivals.

4.) A good deal of Cylon tech is technorganic, including their FTL controllers.

5.) Good old fashioned monotheistic fanaticism, with a tinge of resentment towards humanity.

6.) No difference at all with humans outside and I doubt the Imperium cares about genetics research enough to find out inside.
