Both result in Mom and Dad no longer living together with their children.
Divorce ends a marriage, and annulment results in a legal and religious ruling that the marriage does not exist and never did. If you were curious, modern law has been passed by the legislatures in most, if not all (I haven’t bothered to research that question), so that children of annulment are not made illegitimate by the fact that their parents marriage was annulled.
In my opinion, I don’t believe the difference between a divorce or annulment are distinctions that most minor children would appreciate or understand. The effects of divorce and annulment are, for all intents and purposes, the same on minor children.
