Both images are very good. IMO the low-res version [1] has slightly better colors, while the high-res version [2] captures the cloudy weather a bit better, but they feel about equally appealing to me. Note that the high-res image is also very stylized for appeal rather than realism, no one would mistake it for a photo.
