Who is stronger, One Piece Sauron or Luffy?

In the cartoon, Sauron and Luffy met once, and they got into a fight because of misunderstanding. Unfortunately, there was no draw in the end, and Nami interrupted them.

Later, when Luffy and Sauron upgraded to fight monsters, although Luffy's opponent always wanted to be better than peso, Sauron was more relaxed and Luffy often had to work hard.
