I know that this question was already asked. But I will ask again, because this posts 2 and 4 years ago didn't get enough answers and popularity

Who in your opinion was stronger: Crossed Thanatos or Demon Lord (Gaeabrande)?

The first was defeated with 1 Gate of Valhalla and the second with 2 of them. But, are these Gates equal? Shouldn't the one which Valkyria used being MUCH MUCH MORE powerful than the ones which Seiya used? Or the Gates are equal and Seiya with Gate of Valhalla would kill Crossed Thanatos?
