I'm quite sure valid cases can be made in hindsight, for situations where buddy breathing is preferred and just as many cases can be made for using a conventional octo. Going over those will always elicit other scenarios where the writer supports their own point of view. But, that's the best thing about discussing them, we all learn something and further shape our own diving paradigm.
I like using an octo, but then again, my wife is my primary diving buddy and it reassures me she has an octo as well.
