That is not even a challenging question. Revan was much more powerful.

Yeah that's what I believe as well. But someone actually tried arguing with me the other day that he was bantha poodoom in comparison to Palpatine. So I just wanted to see if this was a common belief or not.

If you actually look at the Sith knowledge that was available at the time of Revan. Most of that was lost by the time palpatine was around so palpatine didn't stand a chance. Also Bane found the secret for eternal life from Revan's holocron. What did Palpatine do?

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.
