A lot of people saying it doesn't matter which one you go with, and that's mostly true, but "The best camera is the one that's with you" and mirrorless cameras are lighter and smaller. The weight and size difference may or may not be significant enough to determine how likely you are to bring your camera with you, but for me it's the difference between bringing it on a hike or leaving it at home.
