Damn, that's a tough one. Let's see...
I like The Hand's design and powers, Purple Haze could have been great if it had more screen time, and I love the comedic duo of Oingo and Boingo's stands.
The Lovers are also underrated imo
Star Platinum has a special place in my heart just because of the scream after Jotaro defeats N'Doul lmao
What about you bro
