Yeah, it doesn't appear that PSSR (which I cannot help but pronounce with an added i) is the highest quality upscaling out there, combined with console gamers not having experienced FSR/FSR2/FSR3's uh, specialness is leading to people being confused why their faster console looks worse.
Hopefully Sony does something about the less than stellar quality in a PSSR2 or something relatively quickly, or they're going to burn a lot of goodwill around the whole concept, much like how FSR is pretty much considered pretty trash by PC gamers.
Upscaling definitely has it's moments, but it can be extremely obvious when it's being used too. Some real ghosting can happen and can take you out of it, and fine tuning for your hardware and each game takes some time. I can see them trying to do a "one size fits all" for consoles, but people are going to have different takes on it. Some will barely notice, others obviously here it will be jarring and weird.
DLSS seems to be virtually immune to these issues, unlike all of the alternatives. I've been an obsessive pixel peeper for decades and am having a hard time finding any faults with it. In fact, it usually improves image clarity and stability.
