Sam!
You've decided that "mirrorless SLR" is the answer to any question. A reviewer must overcome personal bias. Doing so means that what the camera is used for and the output quality for that use is the #1 issue. If you review cars that can drive to the grocery store for apples, every one can suffice. If you want top quality handling in the curves and a 0-60 mph in less than 5 seconds, the field narrows considerably.
For me, the sharpest and best lenses used with a higher 36 MP sensor in my Nikon gives better "pro" quality pictures of landscapes, product photography, weddings/portraits, action, etc. My Nikon D800E/D810 can take pictures comparable to my old 35 mm film cameras and medium format size too.
