They both have 3d audio chips, both support RT, both have SSDs, what is new in PS5 that’s not in XsX?
Arguably Sony invested a lot more in their "3D Audio" take a look at Sony's 360 Audio Reality which is the base of the new Audio "system" of sony, it's actually revolutionary and not just another 3D Audio engine, those exist years now, it's not the same.
Also the SSD Tech is just not comparable even if a lot of people compare them, Sony is pushing the technology forward with this machine and sooner or later people will realize it, I know I'll get some lols for this comment but it's just the reality and blind fanboyism won't change that, honestly I would love more TFLOPS on PS5, but a slight better pixel count doesn't change your experience in couch gaming, except if you play on a monitor, else the difference side by side is miniscule and almost not observable.
Excuse my grammatical errors but I am overworked and can't focus since English isn't my native language.
