The second one is better IMHO, perhaps less saturated but slightly more contrast. But I'd also work on the waves a little more. Perhaps have some really large displacements, to get huge swells, at the same time making it less rough. So some large swells would go higher than the horizon, others not. There's not really depth in the water (towards the distance I mean). And a group of seabirds...
