From those screenshots, Alan Wake is better.
However, all of those for Alan Wake look suspiciously like they're cutscenes. A quick look at other screenshots reveals that nothing that looks like active gameplay has the nice lighting or camera focus effects of those screens.
I don't think many of the Uncharted screenshots are in-game action either, although it's a bit harder to tell - it looks like they at least used the same graphics engine to create the cutscenes.
