Most people probably not going to see the difference between a XSX and PS5 game unless u put it side by side. For most people everything will just look good. Higher resolutions and stabler framerates can also come from developers, having a bit extra power means you can worry about optimizing slightly less. Someone used an extreme example of 1 vs 2 seconds load times but it can be 4 vs 8 or 10 vs 20. Users are impatient and if it's games where they keep dying or need to fast travel a lot, they can get overly frustrated with load time. Then there's the times when you aren't in a loading screen, when you are streaming data, when you are going super fast in some video game city, and your console is able to pull in a significant amount of data very fast and the game is able to dynamically show you more things around the city at full details right away giving a better more immersive experience. When your character turns around and you can load it completely different assets. Loading ~9GB of new data within a second or ~5.5GB/s in a split second can allow developers to dynamically change what shows up on your screen without any visual hiccups. Also, in general the more negligible you can make the loading times, the more time game developers can spend on the main game instead of working on obscure in-game loading screens (e.g. elevators). Then there's all the benefits at the system level that may make the PS5 a slightly better user experience for download/installs/patching. A bit more raw theoretical performance is great and all, but developers probably aren't itcing for that extra bit of compute; and reducing the latency and effectively further blurring the line between memory and long-term persistent storage would give the developers more power in what they want to do creatively opposed to achieving arbitrary technical measurements like resolution, resolution, or process extra details that most people wouldn't notice. The one X has 2 extra tereflops than a PS4 Pro. Is it a night and day difference? No. They both look really good but the Xbox One X looks better but again most people probably wouldn't notice unless you put it side by side.
