I have an A8 and an 805 and motion is noticeably better on the Sony A8. The 805's motion settings add artifacts on quick moving content for anything above the minimum setting, where as the Sony no matter what settings you pick it never distorts. That said no one else in my house can tell the difference, and in my experience the 805 is much more user friendly if you're buying and want others in the house to use it who aren't tech savvy (pause live TV, apps all in one place on the home screen, backlit remote etc) but the A8 is a better picture if you're a person who watches closely.
