soempen For a long time I feel the same, for me always there is something off, like color or brightness or always blurry in the scenes from SLR, and ARPorn wins for me in new scenes, for example, when compare same model Octavia Red in scenes from both sites.
Both images capture from master files.

ARPorn scene:

For me, the color and brightness on SLR scene are off when watching on PT and SLR scene is like "blurry", ARPorn fells more real on PT.
SLR always had the best quality on real PT, old scenes like with Lexi Luna ou Jennifer Mendez for me was the GOAT of real PT quality, but something changed after that time.
