Knowledge Plus

While -아/어 봤다 can also express experience, (으)ㄴ 적이 있다/없다 specifically emphasizes the existence or non-existence of a past event or instance, making it a more direct way to state "I have/haven't done X." -아/어 봤다 often carries the nuance of "trying something out" or "experiencing something to see what it's like." For example, "한국에 가 본 적이 있어요?" (Have you ever been to Korea?) asks about the experience of going, whereas "한국에 가 봤어요?" (Have you tried going to Korea?) could imply trying it out. However, in many contexts, they are interchangeable when simply asking about past experience.
