Prince Zote hardest boss?

Might be a controversial opinion but I feel like the boss I have the most struggles with the invincible, fearless, sensual, mysterious, enchanting, vigorous, diligent, overwhelming, gorgeous, passionate, terrifying, beautiful and powerful Grey Prince Zote. The boss is just so different compared to every other boss. It's unpredictable, it forces you to improvise constantly and it can be a bit unfair at times. I don't want to call it a bad boss as I think that it accomplishes as it accomplishes it's goal very well (that being the role of a knight made out of an obsessed fantasy, in my opinion anyway).

What do you guys think?

Note: I haven't completed p3 yet so I haven't encountered the likes of pure vessel or any other p4/p5 exclusive boss. So take what I said here with a grain of salt
