If an event is replaceable (1xxxx or 3xxxx) in most cases you should use the address. This allows editing events via replacement. However, it also greatly weakens the content-addressability and immutability of nostr events, since you're not referring to a hash of the content, just a pointer to something that can change in unexpected ways. So when modeling new kinds, it's best to bias toward using non-replaceable events.
