Thoughts on this JoJo's Golden Spirit tier list now that the game is out?

I’ve been looking through the launch roster and found this JoJo’s Bizarre Adventure: Golden Spirit tier list. It’s more detailed than the usual character tier list since it ranks the best characters separately as damage dealers, tanks, and supports.

The suggested best team comp is Jonathan, Caesar, Koichi, Joseph, and Giorno, but what caught my attention is that several SR and even R characters rank fairly well. Tonio is considered one of the best supports, while Pet Shop, Hol Horse, and N’Doul are all in S tier.

Has anyone tested these characters enough to say how accurate the JoJo Golden Spirit tier list is? I’m especially curious whether the stronger SR options can genuinely compete with SSR characters once everyone is properly built.
