Hmmm....tough call. At first glance I found the 2nd one more appealing, but when I look at them longer I understand what you're saying about the water being more dramatic in the 1st image. The second image works well because the horizontal framing is consistent with the geometry of the bridge, which fills the top of the frame. Framed a little bit more to the right, and down a bit would give the dramatic water found in the 1st image.
Having said that, all three are lovely images.
