I like the default one all right, except for the sky, which looks a bit bland to me (too much magenta and not saturated enough). But the faraway mountain haze (esp. in the shadows) is the most neutral of three, which I like. The second one has a typical Nikon blue sky – looks a bit fake to me (too much green and too saturated), but that’s really personal aesthetics – many people like their skies like that. The shadowy haze is the coldest of the three. I’d pick the dcp version of the sky (maybe back off the saturation slightly), and maybe open up the shadows in the foreground bush/trees (it looks the most contrasty of the three in that area).
