666 would win piss easy because as far as has been shown Samael is simply in an advantage against dragons. It's not actually stronger than them, it simply has and advantage much how like an ice type attack from a much weaker Pokemon can one-shot a Dragonite or Garchomp. Ophis or Great Red can beat 666 individually with raw power, 666 beats Samael too due to raw power, but Samael can damage Ophis and Great Red simply due to a "rock, paper, scissors" dynamic. Samael's curse does not have to do with power levels at all.
