Both have strengths and weaknesses.
Bendis wrote some decent stuff and had great ideas (that maybe didn’t work out quite as good as the idea)
Aaron is the same. He clearly enjoyed his time on Thor, and pushing ideas and concepts like unworthiness and Jane as Thor is what comics should be about. His execution may have been to Thors detriment, but Thor was certainly highly talked about. I see the run on a lot of top 10 lists when it comes to the 2010s.
