For students preparing for the Academic IELTS test: how would you approach this Task 2 writing task?

I have been helping students with their IELTS preparation for many years and encountered this question the other day with a student. For students preparing for their Academic IELTS test: which advantages and disadvantages would you give when planning your answer?

"Some people believe that a great difference in age between parents and children is more beneficial. Do you think the advantages of a greater difference in age between them outweigh the disadvantages?"
