Bane got his inspiration for the Rule of Two from Revan's Holocron. It was Andeddu's that taught him the secret to eternal life. But Palpatine and Plagueis figured out how to manipulate midichlorians within an organism. That's how he was able to kill Padmé from across the galaxy. He also used Andeddu's teachings to keep bringing himself back form the dead, using clone bodies. But yeah. Like I said. I agree. Revan was the more powerful.
