I prefer the first one - the sky is much better than the second shot, though the composition of the second one is quite appealing. I might add a little contrast to #1 and see how you like it. Contrast will make the sky in the second one less attractive, so I wouldn't fool with it, or just add contrast to the land. Conversely, I might try bringing the brightness in the second sky down a notch and seeing if it works for the image.
