My favorite is the second. I can't believe I'm saying it, but I like the muted quietness of the image. You see the monument, you see dock. All else is nice but not competing with those two objects. And I really like that branch creeping in from the left. While I like them all, the first one's "bars" keep interfering with my view. And on the bottom one the reflection, clouds and color/contrast are SO strong, that I find them competing for my attention.
