Both use subpixel rendering is that it is specific to the display where it is shown. You need the same subpixel ordering and you can't really scale it. Your preference may be correct on your display, while mine is correct here: I strongly prefer the second image.
The first image has less hinting, causing the top of the x-height to be rendered at a half pixel. This makes it seem less intense that the rest of the letters. The second image aligns way better and have a more consistent intensity and sharp edges, but gives an overall slightly more bold appearance, and also compromises a tiny bit on the actual shape of letters.
