Well if it's all been decided by the literary academics then what's the point in asking the question
Seriously though, it is a bit of a redundant question. Art is subjective, it's not a competition. The life and experiences of the author are unique, the influences they have and the time in history they work in are all different, as are the reasons for pushing the boundaries of their writing.
Therefore it's impossible to properly compare one writer with another and what in the end does it achieve? Very little in my opinion.
