Lightroom 3 100%
Started noticing a bit of a "painted" look to some visually noisy images in Aperture. Not noisy from high ISO, but noisy as in lots of stuff going on, like tree leaves or blades of grass, etc.
These are imported straight out of the camera, no edits other than the default imports automatically applied by Lightroom/Aperture.
Immediately you can see there's a slight bit more crispness to the image in Lightroom. Adjusting Aperture's sharpness to match the default Lightroom applies did not do anything to help.
