Fizzbuzz requires you to read and understand a few lines of requirements. That is much harder than just "order these elements, runtime isn't important", you can easily miss some part of the problem statement or misunderstand it for Fizzbuzz and fail, you shouldn't but it can happen, no such thing for a quadratic sort.
