Practice JLPTHow to tell them apart
のに expresses simple contrast against expectation and is neutral, usable about people, things, or situations. くせに carries the speaker's contempt, anger, or blame toward someone's action or state, so it sounds judgmental and is mainly aimed at another person. Swapping them is unnatural when the subject is an object or yourself, since 高いのに美味しくない is fine but 高いくせに美味しくない sounds odd, and くせに implies criticism of a person's behavior.
- のに Use のに for neutral contrast about any subject, including objects and yourself.
- くせに Use くせに when you feel contempt or blame toward someone's contrary action or state.
