One has to be careful since if you're not looking with a properly calibrated monitor it can really skew the results.+1
On my monitor, I personally like the second. I find the first is a little too "HDRish" for me. For post I prefer when the average person can't tell that any adjustments were made. It's just my taste. As a result, I tend to be very "sensitive" to HDR gone wild.
Don't get me wrong, both are beautiful shots, I just prefer the second.
