That's what I keep hearing from Lightroom users (who don't use Photoshop or barely touch it).
Which is better? or are they exactly the same? I'm not referring to a specific version, but I am personally using the latest Cloud versions of everything. I haven't tested it visually, I'm just now getting familiar with Lightroom.
Given the same version number, Lightroom and Camera Raw have the exact same sharpening and noise reduction. The only differences in ACR and LR are usability or UI aspects, the controls and rendering are the same.
