I think it is relatively easy to choose. With the PS3 you get the best video quality, either by streaming mkv files, or by watching Blu-Ray Films. The AppleTV is more capable for occasional watching of movies and browsing iTunes content stored on your PC. While I agree that the quality is good, it is not the best my FullHD TV can do. For the movies that I love, I use my PS3. the AppleTV is used for the rest...
