Who do you think is more powerful, Dumbledore or Voldemort? Why?

Albus Dumbledore because Voldemort feared him and Dumbledore knew better he knew about the prophecy and he could love after all love kept Harry alive when he was born. And they were both half bloods so Voldemort can't even one up on that. But in a duel dumbledore would have a small chance of winning because Voldemort used the Unforgivable curse's and Dumbledore would not but Dumbledore had the elder wand making it more even.
