They seem interesting, since their Stands are similar to Green Day and Oasis in general function but not form, whereas Doggy Style just feels like a straight-up worse version of Stone Free.
Actually, a lot of Part 8 Stands feel like weaker versions of other ones: (As opposed to Part 7's In A Silent Way being a stronger Echoes and Listen To My Rhythm being a different, but not strictly better or worse Killer Queen.) Speed King can do 1/20th of what Weather Report can, King Nothing's entire ability is akin to Highway Star's side-effect of granting its user a strong sense of smell, California King Bed is like a ridiculously over-complicated Jail House Lock, Fun Fun Fun is a more restricted Justice, or even just how Sky High can control people's bodies indirectly. Nut King Call and Sticky Fingers do similar things, but neither is strictly better than the other, I don't think…

Schott Key no. 2 is a nerfed version of Purple Haze.
Love Love Deluxe is a highly nerfed version of Love Deluxe.
I am a Rock is a nerfed version of Ticket to Ride.
And my personal favourite: Killer Queen is a nerfed version of itself from Part 4!
