It depends on your experience, familiarity with the tools, and nature of the change. For example, you might think a single character change would be faster in nano, but that’s not necessarily the case. By the time you’ve moved the cursor using the cursor keys, deleted the old character, and typed the new one, an experienced vi user could well have made the same change faster. We can all think of far more complicated changes that are considerable more efficient in vi. So the question is 'given perfect familiarity with the tools, and all else being equal, what kind of changes, if any, are more suitable for nano rather than vi. None of that is to say that nano doesn’t have a place.
