Since in Michigan, green tends to be a predominate color, I stay away from the landscape setting beause it tends to push the greens too much, and in the fall we get a lot of reds that get clipped. On average, I like the Adobe setting. However, I think the blues in the sky do tend to look better with the landscape setting. In the end, I think it is the color content and composition of the picture that dictates what setting to use. For example, a mountain shot with little green (or dark greens like conifers) and lots of blue sky may look better with the landscape setting. But I am not sure there is one setting that is good for all.
