All this comparison is a bit premature ... if any of these writers, regardless of the genre, form, etc. are still being read and/or listened to as Shakespeare still is today, then, I’d say we have room to say they are of all time. Then again. We’ll never know. If it means something to you, that is the true measure today. I know there are things I listen to again and again and have for decades. Similarly, I also re-read certain authors works in the same manner. It makes no difference if others do.
