Number three for me. I think it has the most appealing colour rendering, and that's what I personally care about most. This is based on the assumption (without seeing the exif) that the shots were taken towards evening and that the pinkness in the sky in the third shot is natural. If that's the case, then the blueness of the far hillside would also be natural as it would be in quite deep shadow.
If my guess about it being evening is correct, that means that the first two shots have been overly white balance corrected by the cameras and have lost any sense of the natural light. But of course if the shots were actually taken at mid-day and the colours in the first two are accurate, then the third shot must be suffering from a severe colour cast.
Looking forward to the big reveal.
