I prefer the 1st image. I think it's more dramatic, and the lack of detail in the rocks/water at the very foreground compared to the clarity of such in the second shot leads the eye straight to the large rocks, through the water and to the beautiful sky.
Just my personal taste, though.
I also agree the sky in the 2nd shot is a bit blown out. The second shot might benefit from a reduction in exposure (or added recovery) in the sky, and possibly a crop of the sky itself so there is less of it. I think that might create more of a focus on the foreground with the clear water and small rocks, which I do find interesting, but I find they compete with the overall landscape composition.
So for a landscape I prefer the first image, but I think the 2nd image with a bit of work has merit on its own to highlight the interesting detail in the foreground.
