[wh40k] At the absolute peak of their power, what race is the most powerful?

Saw the recent post about the most powerful race (Tyranids, apparently). I was wondering if things change if you consider each race at their peak, i.e., Man with a functional Emperor, the Eldar before the fall, etc.

Necrons were able to subvert the C'Tan, star-eating sentient beings. Eldar in their prime forced the Necrons into stasis. Tau have no prime because they are relatively new. Humanity at its prime had technology beyond that of the Necrons and were able to go toe-on-toe with the Eldar Empire. The Orks are currently in their prime. Tyranids need only wait for their main fleet to overwhelm everyone with numbers.
