If OP is looking for an antonym that includes some negative connotations I suggest kudos.

In my experience kudos is often used somewhat disparagingly, with a suggestion that the reputation being refereed to may in fact be overrated or undeserved?

In light of subsequent clarification from OP, I suggest. hallmark. A phrase which can to be used in exactly the same way as some other offerings, and sometimes it’s used in reference to undesirable qualities, sounds good; “The hallmark of industriousness is associated with rich people”

sounds good to me.
