it's not just about 'look' in the sense of fine grain/reduced noise, but about being able to make use of wider apertures in bright light. Especially with sensors smaller than 35mm, when the depth-of-field is so pronounced. On a sunny-16 day you'd struggle to shoot less than f/4 or f/5.6 at ISO 200.
