It's been my experience that the best photographers almost always value the handling and ergonomics of a camera over some tech specs like MP (assuming that certain minimum standards have been met, which with today's cameras almost always applies.).
I am certainly not one of those best photographers, but I know when I am out shooting, usually my ability to know and operate my camera becomes more important than MP or other technical capabilities of that camera, because all of the camera are so advanced anyway. A lot of that is on me, but it does help to have a camera with a great design, user friendly controls and menu's, etc.
Canon has mastered the user experience moreso than most other brands, and I think that is why they have been number 1 all of these years.
BTW, someone noted this in another discussion a while back: amateurs care more about the specs but don't know what to do with them.
