I have used all three lenses on a Canon 7D MK II. In my opinion, the Canon beats both of them with respect to image quality and also price, lol. The problem I have now with the Canon lens is it creeps. I have been unable to place a lens band on the end of the camera where the lens extends because when I do I am unable to auto focus. If I move the lend band back a little further on the lens it doesn't do the job. So, I live with it. Good luck.
