If you are shooting for anything above 30fps, he wasn't categorically wrong. Zero Dawn is in some ways a better looking game on PC at Max settings and @ 60fps compared to the Forbidden West running in performance mode on the PS5. Not all aspects of course, but it definitely is a cleaner image with higher rendering resolution, better shadows, and higher texture quality. These are just statements of fact and I wouldn't resort to calling someone a dumbass for pointing these differences out, which is exactly the point he was making.
Of course you are going to have better Art, Character Models, and animation on Forbidden West, but that is more due to the advancements in their underlying technology the game was built on. IIRC, these points were not disputed.
edit: point being in many ways this is a subjective matter. If someone preferred clean IQ, then they are going to think the PC Version of Zero Dawn looks better. Of course this also means that if one is fine with lower resolutions and upscaling artifacts, the better animations, art, and character models of Forbidden West is going to win out.
