Placing the peak in the center of the frame gives a somewhat static feel. Also the greater width makes the sky seem more cramped. The crop places the peak in a more pleasing off-center position and increases the height of the sky relative to the remainder of the image. With Photoshop CS5 you could use context aware fill to build a little more sky at the top of the frame. I believe that would help the compositional balance on both the original and cropped images, although the peak position would continue to favor cropping from the right. OTOH, adding a little sky to the original retains much of the pano feel, whilst adding sky to the cropped version moves it into the more conventional ration image range.
