Who is the strongest boss in Elden Ring now that Shadow of the Erdtree is out? The debate among fans

In addition to debating the game's difficulty, Elden Ring fans are arguing about which is the strongest boss in the entire game now that Shadow of the Erdtree has been released.
If the debate on the difficulty of Shadow of the Erdtree wasn't enough for you , now there's another one that's taking center stage in the Elden Ring community: which is the hardest boss? The issue, which had been resolved at the time of the base game by placing Malenia on the throne, has now been reopened with the arrival of at least one truly fierce contender.
